Ironwood Seeds - Sonoran Desert Delicacy


When I researched the Tohono Oodham Nation, one of the foods they foraged in the Sonoran Desert was ironwood seeds, so I decided to find out what I could about this food source.
First, about the trees. There are many trees known as ‘ironwood’, so the version found in the Sonoran Desert is often called desert ironwood. The tree itself grows extremely slowly, and can possibly live for centuries. But even after one of them dies, it might remain a landmark for millenia. This is because the heartwood is so full of toxic chemicals that decay is practically eliminated.
The seedpods grow from the middle of a stem, not the end, and each pod can hold up to a dozen or so seeds. The pictures I saw depicted a brown pod that reminded me of a cross between a green bean and a smooth-skinned peanut pod. Or possibly a vanilla bean pod. The seeds inside seemed to have a passing resemblance to peanuts, which seems fitting, since both the peanut plant and the desert ironwood are legumes.
As with other legumes, the desert ironwood enriches the surrounding soil with nitrogen, so the area immediately surrounding this tree is richer for growing plants than the soil another couple of feet away from the tree. Did the Oodham tend to cultivate their crops by planting them in close proximity to an ironwood? I don’t know, I haven’t found any information on that. But in my mind, it would make sense for them to have done so.
Now, about those seeds.
Ironwoods generally flower from late April through May and set seed pods a few weeks later, which will dry in June-July. The flowers, fresh seedpods and dried seedpods are edible.
The pink flowers can be used in or as a salad. They can also be candied for use as a dessert, but I don’t know if the Oodham did that. Good to add to my basket of knowledge as I look for means to feed an alien culture.
The seedpods are apparently beige from the start, so how do you know when to harvest them if you want them fresh? You open up one pod and look for the seeds inside to be green. If the seeds are sweet and taste slightly like a peanut, you are good to harvest. Gently pull whole pods off the tree.
However, if that seed tastes chalky, you’ve waited too long to harvest them as fresh. Go away and come back when the pods are fuzzy, dry and dark brown. The seeds inside will now be hard and brown. Don’t bother picking the pods by hand at this point; just put a tarp or blanket on the ground and gently shake free the dry pods. But don’t harvest any dry pods that land on the bare ground.
Whether you have harvested your ironwood seeds fresh or dry, they should be cleaned and processed for storage as soon as possible after picking to reduce the chances of spoilage. Now, I got some information from a website (see below) on how to do this, but the instructions as given require things I’m pretty sure the Oodham did not have in yesteryear. Things like ice water, plastic bags and a freezer. Suffice it to say that they suggest you blanche the fresh seeds, package them in bags with as little air enclosed as possible, and throw the bags in the freezer. Even the dry seeds need to be frozen for at least 2 days to avoid bug infestation.
So I’m guessing the Oodham didn’t process them that way. I’m guessing they merely cooked them using their favorite method and ate. And the next day, somebody would go and forage again. Maybe they came back with more ironwood seeds, maybe they found something else.
All good to know when I’m trying to keep somebody alive on what seems an inhospitable planet.

What is This World Coming to? 4


Okay, we’ve spent quite a bit of time exploring melting ice and (some of) the resulting changes to The Oceans As We Know Them. And last time, we touched on the Arctic jet stream, which brings us to the atmosphere. Let’s go ahead and explore (some of) the changes we can expect there.

I just heard on the news tonight that Hurricane Willa - born in the Eastern Pacific Ocean - will tear across the middle of Mexico (despite the mountains) and then hit the south and south-eastern areas of the US. It’s not expected to be a hurricane by the time it gets to the US, but I don’t remember hearing about any Pacific hurricane/cyclone/typhoon doing that before. And anytime hurricanes get mentioned anymore, there always seems to be a cat 5 hurricane that somebody is watching. Some of them have been so strong a cat 5, there has been talk of defining what would make a cat 6.

The average global temperature has risen 1.4° Fahrenheit (0.8° C) over the past 100 years. Now, that’s not 1.4° F for every single location on the globe. Temperatures at the poles have risen faster than other places. But that is a big change over a short period of time, when you are talking about the life of a planet.

Consider the northern plains of China, home to 400,000,000 people, and the place where much of China’s food is grown. It doesn’t get a lot of rainfall, when compared to southern China, so the fields are irrigated during the growing season. Research from MIT indicates that the temperature in this area of China will cross above 95°F several times between 2070 and 2100. At that temperature and with the added humidity caused by irrigation, even young and healthy humans would reach the point where their bodies could not cool off, and death would result within a few hours. And that’s the young and healthy. Old and frail wouldn’t last that long. Do you suppose they’ll farm at night? How would the plants they try to grow fare in that kind of heat?

Shanghai, on China’s central coast, would cross that 95° F threshold about 5 times, and approach it over 100 times during that same time period.

In the Middle East, many areas, especially coastal cities, are in the same mess. In 2015, Bandar Mahshahr in Iran almost reached that ‘death threshold’ when the temperature hit 114.5° F with 50% humidity. Only 50% humidity! But when the temperature gets high enough, the human body can’t function.

What else can we expect? Some areas, like northeast US, may experience an increase in rainfall, while in the northwest US, rainfall will decrease. Washington has been experiencing range fires the last few years, but I don’t remember hearing about them before that. Maybe I wasn’t listening. But I do know that California has been in a drought for several years, and they’ve had fires rampaging across the countryside.

Not a pretty thought, looking at the future and what climate change will do to us. I have a lot of thoughts to piece together for that book I’m thinking about.

I’ll be looking for information about what food will be able to be grown where in the next 50 years. If I find anything interesting on that front - or some other front I haven’t thought of - I’ll continue this series. Otherwise, I’ll wrap this up next time.

Harvest Feast

Thanksgiving Day in the US is traditionally a day of over-eating. Each family develops their own quirky traditions in what they eat and do on that day, but over-eating is generally common ground.
In the US, legend says early colonists did not bring enough supplies, so half of them (50) died in that first winter. But friendly natives helped the rest survive after that, teaching them to catch eels and grow corn. Before their second winter, they harvested plentiful crops, and hunted wild birds and deer, so they had full larders. And for 3 days, they over-ate in joyous thanksgiving.
Basically, they were celebrating a good harvest. And harvest feasts go back a long, long time, at least as far back as Ancient Egypt, possibly as far back as when man changed from hunter/gatherers to farmers.
It makes sense; after a good harvest of the main crop, food was abundant. There wasn’t as much work to do in the fields, so the workers had more leisure time. In some cases, the coming months would be cold and dreary. Keeping all that food in good condition might not be easy. So it was natural to celebrate in having plenty of food.
Over-eating in the fall could also give them extra fat, which could help protect them from the cold, and give them extra calories to burn, should things get lean before anything became available in the spring.
But what if future colonists landed on a planet with different seasons than Earth? For instance, the winters are so mild, this is when the crops grow. Harvest is held during increasingly hot days, as the climate turns into a blistering summer where Earth plants struggle to survive, and the colonists stay indoors to avoid heat stroke - or worse.
When would they celebrate? I am assuming storage of crops would not be a problem. Would they feast at the end of harvest? Gain a few pounds of fat to lug around through the sauna-like summer? I don’t think fat is a good insulator to keep a person cool.
Or would they wait until the temperature starts to dip, and they will soon need to prepare the fields and plant the crops? To do that, maybe they could use some extra calories to get all that hard work done. Plus, they would have an idea just how much food they could use for a feast.
That assumes the colonists are doing hard, menial labor themselves, not sending machines out to do it. Perhaps they are. Maybe there wasn’t room for farming machines, or the machines are broken.
Would they think things through and have a delayed feast? Would everybody agree to that, or would the question breed dissent, even anger?
Or would they just follow tradition and feast right after the harvest? Would they eventually learn to delay that feast?
I see story possibilities here.

Have a great Thanksgiving. Only our youngest son will be joining us this year, coming over early enough to help with the cooking. We won’t be watching football, so we’ll be debating which sf movie disc to put in the machine. That’s one of our traditions. A quiet Thanksgiving is still Thanksgiving.

Have a Heart

Heart transfers have been part of the medical scene for a good chunk of my life.
Donated hearts, along with other organs, used to be (and still are) ‘harvested’ from a donor, packed in ice and rushed to the recipient. But the waiting list is loooong, and many people die while waiting for a new heart.
Australian doctors have harvested a heart from the recently deceased - 20 minutes or less - placed the heart in a special fluid, resuscitated it, and kept it beating until it was placed in the recipient patient.
They have done this 3 times. The first 2 recipients were doing well, the most recent patient was still in intensive care after the surgery. The doctors stated that with this process, with the heart actively beating right up until placed in the new body, they know the heart is good, that it hasn’t deteriorated past the point of use.
When I mentioned this article to my husband, he made some comment about, ‘Dr Frankenstein must be living in Australia these days.’ Always ready to see the funny side.
I found this report a bit creepy, when I first read it. But after further reflection, it dawned on me that all donated hearts come from dead people. Nobody has a spare one they can donate while still alive. If anything, the brain dead person who is still breathing and heart is still pumping through artificial stimulation is slightly closer to being alive than the gruesomely decapitated person from the car accident that just happened on Interstate 2 (for example). So the idea lost its creepiness.
In the old method, the heart dies as soon as it is removed, and it remains dead until it is sewn into the new person and jolted back to life. In the new method, the heart still dies, but it is resuscitated and nourished until time to sew it in the new person. The patient still gets a formerly-dead heart, but it hasn’t been ‘dead’ for as long.
Okay, I was wrong. Thinking about it like that makes both ways creepy. But it works, and if it saves more lives without costing any extra lives, then I’m all for it.
I still think the ideal thing to do would be to take some cells from the patient who needs a new organ, put those cells in a nutrient bath and coax them into growing a new heart/liver/whatever for that patient. I would think that would avoid rejection, too. Maybe they’ll get to that, some day.

While I’m waiting, I’m making a list of the parts I’d like grown for me. Let’s see, both knees, right shoulder, pancreas, gall bladder... Since I’m making a list, is there anything you’d like to order?

Holidays - Turkey Day

I'm writing this on Thanksgiving. It's a holiday we enjoy in the States every November, to commemorate the Pilgrim's survival of their first year in the new world. And, as usual, I wonder if any of my various universes would have a similar holiday.
Let's concentrate on Thanksgiving; it is an autumn holiday with lots of food and reflection on all the things we are thankful we have. Before the Pilgrims, a lot of cultures had a harvest feast. The hard work of raising crops was done, and (some) people could now 'coast' through the winter until spring, when it was time to plant and hope for a good crop. But keeping a bountiful crop stored all winter was hard; mice and mold and who knew what else could claim a good portion of it, so feasting might continue well into the winter, until most of the food had become a layer of fat on the people, which would help them survive those last few weeks until they could get their hands on fresh food again.
Mac (MacOnFireball.blogspot.com) definitely does have a Thanksgiving, because the Fleet follows the majority of the Earth traditions, but whether it is called Thanksgiving, Harvest Day or something else, I haven't decided.
In my Atlan universe, a 'god' (alien) brought 3 infants to live on a remote island, and stayed with them until they could take care of themselves. This island did not have seasons, so there would have not been any harvest time to celebrate. Later, after the home island was destroyed, and a few Atlans were scattered about the planet to establish tribes, each tribe might have a day of celebration. Some might celebrate the day they made landfall, or others - who now experience seasons - might celebrate a successful harvest.
In my Tunad universe, I think they might have 2 holidays that resemble Thanksgiving. Their colony is established in early spring, and they celebrate the anniversary of that day. They would also celebrate the first fall harvest, which proved they could raise food on a planet that was much colder than their home world. But the Tunads were very careful choosing holidays as they set up their calendar. They did not hang on to any holidays from their home planet, as they have set out to escape from that culture. Still, they recognize that holidays are important, a way to say, 'Our hard work has paid off,' and 'See how far we've gotten.'

Hope you had a great Turkey Day.
