Where to classify grocery expenses for food blog?

If I have a food blog, in which TurboTax category I classify the grocery expenses I sustained to prepare meals I prepare in connection with my food blog? I see "Supplies" or "miscellaneous expenses"; I also see "Inventory", but it explicitly says "Only enter the amounts paid for products held for sale" and I do not plan to sell meals, only to prepare meals and showcase them on the food blog.
