This makes it an ideal choice for delicate baked goods, such as cakes, cookies, and pastries. Additionally, cassava’s high fiber content helps to improve the texture and structure of gluten-free baked goods.
Another significant advantage of using cassava in gluten-free baking is its ability to bind ingredients together, eliminating the need for xanthan gum or guar gum. This makes cassava an excellent choice for gluten-free bread, pizza crusts, and other yeast-based products. Furthermore, cassava is relatively inexpensive compared to other gluten-free flours, making it an accessible option for those on a budget.
How do I cook and prepare cassava for gluten-free recipes?
Cassava can be cooked and prepared in various ways, depending on the desired texture and flavor. To use cassava in gluten-free recipes, it’s essential to peel and chop the root into small pieces, then boil or steam it until tender. Once cooked, cassava can be mashed, pureed, or dried to create a flour-like consistency. Cassava flour can be used as a 1:1 substitute for wheat flour in many recipes.
When cooking cassava, it’s crucial to note that it contains naturally occurring cyanide compounds, which can be toxic in large quantities.
