Making Tofu:
Tofu is made from soybean curd which has been pressed into a block shape, then stored in a brine.
To make soybean curd:
1. Grow soybeans (A LOT of them)
2. Harvest the beans
3. Remove from their pods
4. Soak the soybeans in water overnight
5. Remove the hull from each soybean
6. Puree the bean and with clean water until it's 'soymilk' - a liquid emulsion
7. Strain it to make sure all solids are removed (in case you missed a seed hull or two) - but keep the liquid
8. Bring to a boil and skim off foam (about 5-7 mins)
9. Lower to a gentle simmer (about 20 mins), stirring gently, then take off the heat
10. Dissolve the coagulant of your choice in a cup of warm water - the MOMENT it's completely dissolved, begin pouring into the stovetop soymilk.
11. Gently stir the
milk & coagulant for about 1-2 minutes.
12. Allow the mixture to sit undisturbed for 15-25 minutes.
While the mixture sits, small white curds will separate from amber colored liquid.
13. Once the process of curd-forming is complete, transfer the curds into a molding container lined with cheesecloth or a similar fabric.
14. Fold the fabric over the curds and place a small weight on top to begin pressing out the liquid. Allow the mixture to be pressed by the weight for 20-30 minutes or until it holds together.
15. Remove the block of tofu from the mold.
16. Store in clean, salty water until you're ready to eat it~
Coagulant options:
Gypsum OR Liquid Nigari / Nigari Flakes / Epsom salts (Magnesium Chloride)
Gypsum tends to act faster and results in a firmer tofu.
Freezing the tofu and thawing it again before cooking will help it be denser/meatier/absorb more flavors.
One pound of dried soybeans can yield up to 20 small blocks of tofu.
National average yield per acre is about 50 bushels per acre.
1 bushel of soybeans = 60 pounds
so 1 Acre of soybeans is 3,000 lbs of soybeans
or 60,000 tofu blocks (and a LOT of water)
If you had a 100 sq ft garden (10ft by 10 ft) and ONLY planted soybeans, and got an ok yield, you'd get about 6.8 lbs of soybeans, or 137 small tofu blocks.
(remember: husks and hulls don't count here. We're only looking at unshelled beans)
Making Tempeh
You can use soybeans, or almost any bean, grain, or large unshelled seed to make tempeh.
Making tempeh is a process of controlled fermentation. The beans are inoculated with a starter culture that contains Rhizopus mold spores (either Rhizopus oligosporus or Rhizopus oryzae), and then fermented at a warm temperature. As the mycelium grows, it binds the beans into a dense, white cake.
Tempeh
should be made in a vented container with the beans lightly packed and no more than 1 inch deep. The vents must be large enough to allow for air circulation, yet not so large that the beans dry out.
In order for the mycelium to grow, the beans must be kept at a temperature between 85° and 90°F for 24 to 48 hours. If the temperature is not warm enough, the tempeh spores may not grow and you may get unwanted bacteria. Conversely, if it is too hot, the spores may die.
1. Soak the beans overnight
2. Remove the hull & split the beans in half if they're large
3. Drain the beans, transfer them to a large pot, and cover by 2 inches with fresh water. Bring to a boil.
4. Skim off and discard any foam or hulls that rise to the surface.
5. Reduce the heat and simmer, partially covered, until the beans are tender (about 45 minutes)
6. Drain the beans.
7. Spread them out on two towel-lined baking sheets and pat them dry.
8. Let the beans cool to below body temperature.
9. Transfer the beans to a clean, dry bowl. Sprinkle the vinegar over the beans and mix well. (to help prevent unwanted bacterial growth)
10. Sprinkle the tempeh starter over the beans and mix for about a minute to distribute evenly.
11. Put the beans in their containers.
12. Place the bags in the incubator. The temperature must be between 85°F and 90°F for the next 24 to 48 hours, so periodically check to make sure the temperature is consistent.
13. Between 12 and 24 hours you should start to see some white mycelium growing on the beans. You may want to lower the heat source because the beans will start generating their own heat as the mold grows
14. Depending on your conditions, the tempeh may take up to 48 hours total. The mycelium will continue to thicken, forming a white layer around the beans and binding them into a dense, firm cake. The tempeh is done when the entire surface is covered with dense, white mycelium (some black or gray spots are okay), as well as the spaces between the beans. The beans should be bound together firmly as a cake. You may want to slice a small piece off the edge to make sure the cake is firm all the way through.

The words "I want to make beef/steak/chicken/turkey from plants" confuses me.
You can make very savory, dense materials that you can use /in place of beef/, which can fulfil a similar role as beef in many recipes, but beef is cow muscle. You can't make beef out of plants.
It's like saying 'I want to make a solid gold ingot out of quartz' <--- you can make a quartz bar in the shape of an ingot and treat it with chemicals to appear gold, but it will always be
quartz.
Are you looking for a texture mimicking? Are you looking for a similar savory flavor? do you want big crumbles or little crumbles, or a slab of something that you can sear on both sides and cut into strips? Do you want something you can batter and deep fry and douse with bbq sauce?
Those are all different requests, and will get you different answers.
