Meat - I’m a vegetarian, though I take a lot of interest in cuisine, and while I may not eat meat personally, it’s undeniable that it’s a core ingredient for so many beloved dishes across the world. Maybe one day lab-grown or plant-based stuff will be able to serve as a common, cheap, and indistinguishable substitute, because I do want to appreciate all the food the world has to offer while sticking to my ideals as much as I can.
