Not Labeled GF? How to Wash Beans & Grains to Make Them Safer
What if you can’t find certified or labeled gluten-free versions of beans and grains at the store? Is there a way to make them safer to eat?
Here’s what you can do:
Dry Beans. Since beans are relatively large, washing and visually sorting for anything that’s not a bean (e.g. a stray grain) works very well. Washing dry beans before cooking is generally recommended anyway.
Rice and Sorghum. These grains are quite small so this is a little more difficult, but with a fine sieve or colander these can also be rinsed. Always give them a visual sorting too.
Millet, Teff and Amaranth. These are too small to be strained. One approach is to first visually sort, just like with the larger grains & beans. Then, put the grain in a jar with a tight fitting lid, add water, shake it up, and then let the grain settle. Smaller dust-size particles (that could contain gluten) won’t settle as quickly as the GF grain you’re working with. Any grain that floats could be skimmed/strained off the top.
