Goldbaum's all-natural ice cream cones.
Among the products recently introduced by the Brooklyn, New York-based company are vanilla and sugar cones and, yes, waffle bowls and jumbo cones. All of the cones and bowls, made primarily with potato starch, are manufactured in Israel and are vegan, GMO-free and Kosher Parve. The only discernible difference I sensed between the Goldbaum products and wheat cones is that the former lack a bit less crispiness. (The company suggests in that case to warm them up in a pre-heated oven for two minutes.) Otherwise, they are excellent.
Water to Go/Gluten Free Dynasty in Pennsauken has the jumbo cones and several others. The products can be ordered online at The Gluten-Free Mall.
