TVP = Textured Vegetable Protein. TVP is defatted soy beans ground into flour and made into various shapes ( textured ). No flavor. Tastes a bit like dry cereal. Needs to be soaked to be palatable. Most people soak it in some kind of broth to give it flavor before using it. It has been around forever. You can likely find TVP recipe books in your local library ( or online ). Soy Curls are TVP. “Soy Curls” is the name the brand/company “Butler” uses. Soy Curls are made from organic soybeans, have no other ingredients ( at least on the label ), and are several times more expensive than ordinary TVP. Some people like the shape “soy curls” come in. Warning, it is about 5 times more expensive that other brands of TVP. Watch out for pre-flavored TVP. Some use caramel coloring, and some types of that may be carcinogenic. Pre-flavored TVP often has ingredients beyond soybeans, sometimes even wheat gluten. If you have food allergies read the ingredients before buying. You can buy TVP online. Sometimes health food stores, stores similar to Whole Foods carry TVP ( or “soy curls” ). There is a Seventh Day Adventist grocery store in my area that has several shapes, including Butler Soy Curls available in bulk bins.
