There really isn’t a certification for gluten-free products. In fact most unpackaged gluten-free foods are not required to meet any standard. We just strive for the highest possible quality and do our utmost to maintain good processes in the kitchen.
As a gluten-free bakery that also makes products that are not gluten free, we follow the FDA guidelines on gluten-free labeling for packaged foods, meaning that the ingredients we use for gluten-free scones are either inherently gluten free; or do not contain an ingredient that is: 1) a gluten-containing grain (e.g., spelt wheat); 2) derived from a gluten-containing grain that has not been processed to remove gluten (e.g., wheat flour); or 3) derived from a gluten-containing grain that has been processed to remove gluten (e.g., wheat starch).
We’re also over-cautious in avoiding cross-contact, including any unavoidable presence of gluten in a food due to contact with a gluten-containing food (wheat, rye, barley, or their crossbred hybrids like triticale).
That said, what you need to know is that we are not exclusively a gluten-free bakery and we bake wheat products in the same oven that we bake gluten-free products.
