To make this Egg Puff Recipe (Kerala-Style) gluten free, replace the regular puff pastry with a gluten-free puff pastry brand or homemade gluten-free pastry that is suitable for baking. Also check that the garam masala, chilli powder, tomato ketchup, and curry leaves are free from additives or thickeners that may contain gluten. If you are preparing this recipe for someone with celiac disease or a strong gluten intolerance, make sure your baking tray, utensils, pastry brush, and work surface are thoroughly cleaned to avoid cross-contact.
