I often find myself wanting to recreate staples I have in my cupboards or things I repeatedly order when I'm out, but a lot of these convenience items have impractical ingredients that are hard to locate. (rennet, black mustard seeds, matcha powder, etc.) Does anyone have a go to for these types of things? Ordering online is a hassle and I'm not one for waiting. I'm centrally located and don't normally stray far without a specific destination, so I haven't really stumbled across much. Anything would help!
