Actually I think every food you make yourself is comfort food in a rough self-image phase. At least for me doing something myself (and additionally creating something tasty in the process) provides a sense of purpose and self-efficacy which both helps boost ones self-image on rough days.

I personally like baking cake recipes I’m experienced in and/or make some simple food stuffs I’m less prone to fail in.

Custard. The first dish I learned to bake was crème brulée. The simplicity of ingredients contrasting with the precision and careful preparation helped distract me from the fact I’d just failed out of my engineering studies. Meringue as well; wouldn’t want to waste the egg whites!

When I’m baking, it’s biscuits. My family loves em and it’s a cheap and easy dopamine hit when I pull them out of the oven. Oh no, I slightly misshaped one and it’s imperfect! Guess I need to scarf that one down right now! Also your kitchen smells amazing afterwards.

When I’m cooking for myself, it’s congee. A piece of fish or fish balls, some chili crisp, green onions, and furikake and I’ve got a huge, warming bowl of soup that feels like so much more than the sum of its parts.
