Tofu is made by coagulating soymilk (heating it and causing it to curdle, with the use of salts, acids, or enzymes) and pressing the resulting solids (the curds) into blocks. Much like making cheese, the type of tofu dictates how much liquid (if any) is strained from the solids, and the texture of the final product. If you've ever made ricotta, you can understand the basic process of making tofu.
In Japan, restaurants and food vendors make their tofu by hand and each region is known for their own variety. In the U.S., you'll find at least one variety of tofu in grocery stores, and sometimes many more than that. Each has its own ideal uses and while it may not ruin your stir fry to use soft tofu instead of firm, your tofu appreciation will grow as you discover each type's secrets.
This tofu has a lot of moisture. It's best used in dishes where the tofu will be blended with other ingredients or used as a thickener. It won't hold shape well on its own and has a creamy, soft texture. To make things extra confusing, silken tofu can be found in several consistencies, but don't confuse this with the regular, or Chinese-style tofu below.

Regular or Chinese-style tofu
So-called regular tofu is the solid white block sold in liquid-filled containers you've seen next to the dairy case. Much of the liquid has been pressed out and the solids have been molded into a block. It's sold in liquid to help preserve freshness. Available in soft to firm consistencies, this tofu is best cooked in ways it can stand on its own.
• Tofu and Vegetable Pot Pies - A vegan take on traditional pot pie, this recipe uses extra-firm tofu to add to the delicious vegetarian filling.
