There seems to be a consensus here that preparing beverages (tea, coffee, cocktails, etc.) is on-topic here, and that it's included in "Cooking & food preparation methods". However, by the common, non-technical meanings of the terms, beverages are not "food", and preparing them is not "cooking".
I suggest changing that to be clearer. We could either changing it to something like "Cooking & food preparation methods, including for beverages" or alternatively add another bullet point for beverages.
