I'm looking for information on Tempeh, especially how one make it themselves. Any info would be appreciated.
Do you mean tempeh?
Tempeh is a fermented soybean product, grainier and denser than tofu. Making it requires a starter to help it ferment.
Recipes can be found here.
Otherwise, you'll have to move to Arizona.
Tempe is a fermented with the fungus Rhizopus oligosporus, you will need to find a strain or starter to make it in your home. Once you have that, some boiling and some vinegar and a day and a half later you have tempeh.
