When it comes to plant-based protein sources, two terms often get thrown around interchangeably: bean curd and tofu. While they may seem like identical twins, they have distinct differences in terms of their texture, taste, and production process. In this article, we’ll delve into the world of bean curd and tofu, exploring their unique characteristics, nutritional profiles, and culinary uses.
What is Bean Curd?
Bean curd, also known as doufu or tofu fa, is a type of Chinese dessert made from soy milk. It’s a soft, silky, and creamy pudding-like treat that’s often served chilled or at room temperature. Bean curd is created by coagulating soy milk with a natural agent like agar, carrageenan, or gypsum, which causes the mixture to curdle and separate into curds and whey. The resulting curds are then pressed into a block shape and cut into small cubes or slices.
Texture and Taste
Bean curd has a delicate, custard-like texture that’s both smooth and creamy. Its taste is often described as neutral, with a hint of sweetness and a subtle soy flavor. The texture and taste of bean curd can vary depending on the type of soy milk used, the coagulant, and the production process.
