How are rice or corn cakes made (those crackers which are made somehow of expanded grains all stuck together sort of like Styrofoam, which is eaten by persons for health reasons)? These grains I would imagine cannot be leavened by conventional means, such as with kneading and yeast, because they have no gluten. How do they do it?

Most grains will pop like corn, giving puffy, starchy results.
