El Peto Products has been shunning ingredients with gluten since 1988—long before gluten-free became a popular health trend. Its dedicated 100% gluten-free (and 100% peanut free) federally inspected facility churns out a variety of baked goods made with gluten-free flour, from breads to pies. It also supplies those who love to bake with gluten-free baking mixes and bags of rice or corn flour.
