Since changing to a grain-free diet, I have been trying different types of waffles, both sweet and savory with marginal results. I finally found these which are very satisfying. I would say that they even have a better flavor than typical wheat waffles. The whipped eggs and baking powder combine to give the some lift.
They can be made either sweet by adding some cinammin, or savory by using an herb. Thyme sounds good.
