Soy Products

Soybeans present a palatability paradox: double the protein of other legumes, near-ideal amino acid balance, rich oil — yet raw or plainly boiled, they’re strongly “beany,” full of gas-producing oligosaccharides, antinutritional compounds, and a texture that’s firm rather than creamy (they contain negligible starch). Chinese cooks solved this with two fundamentally different approaches: extraction (separating desirable proteins and oil from everything else to make soymilk and tofu) and fermentation (using microbes to consume the undesirable compounds while generating savory complexity). The results — bean curd, soymilk, yuba, miso, soy sauce, tempeh, natto — are among the most versatile fermented foods in any tradition.
