Loving the WIP so far! Reading the reactions between the child and parent put a cheesy grin on my face, and the fact that you can react to what is essentially a small disaster happening near the train station in a nonchalant manner was also amusing.
The whole “cooking style” thing reminded me of a FATE sourcebook called Uranium Chef, that included Bitter and Cool (minty, as well as things like the taste of seaweed) in the mix, as well as a judging system ala Iron Chef. Maybe, taking a page from that, certain clients prefer a certain cooking style more, or have outright dislikes? That might complicate things too much, now that I think of it.
Paprikash, chicken or otherwise.
Creamy polenta, either served on a side or as a bed for meats and veggies, such as chickpeas, olives and mushrooms.
Bulgogi. Beef is the most popular, but any meat is usable. Overlaps with spicy.
