Katz makes bakery products that are GF and delicious. But here’s a great recommendation. Buy Tamar Ansch’s Pesach cookbook, which is ALL gluten-free I believe (as it’s non-gebrochts) and the recipes are wonderful. She has an amazing chocolate cake, and plenty of sides and main dishes both dairy and meat. So many items are now marked certified gluten-free in all the stors. You HAVE to read labels. because sometimes there is hidden gluten (like maltodextrin) in the ingredients.
I use potato starch or corn starch (check the brand, not all cornstarch products are 100% GF), and Corn Chex, crushed, in lieu of breading. Katz makes a great breading though, also. Get dye free Advil, and make sure there is no gluten in all medications that you use. Wheat is often used as a binder or in the coating on a pill.
