Sauces in general are from scratch except in cases where I’ve found a particular sauce to be too much trouble to do at home. So, for instance, Thai curries, which involve just a few too many individual steps for most nights, start with a curry paste held in the fridge long-term.
I do run into fridge space concerns. Arika, my partner, keeps cold brew coffee, Coke, apple juice, half-n-half, and creamer in the fridge full-time. I generally have diet coke, 2% milk, and an energy drink or two handy. Between those, plus really common condiments I keep larger bottles of (ketchup, mayo, red and green salsa, BBQ sauce, and some fancier salad dressings for days when I’m lazy and don’t wanna make a vinaigrette), we’ve basically filled the entire top section of the fridge.
Asian cuisine has also consumed a lot of shelf-space–soy sauce, dark soy sauce, oyster sauce, hoisin sauce, fish sauce, chili sauce, mirin, Kewpie mayo, okonomiyaki sauce, etc., are basically a shelf and a half. Toss in some syrups, jellies, mixed drink fixings like simple syrup and grenadine, and olives/pickles/etc., and all the shelves are already gone. Then the big cheese drawer, random Indian stuff like tamarind sauce and chutneys, and yeah, it’s getting very full.
So there’s basically just one big bottom shelf dedicated to storing tupperwares, plus the crispers/meat drawers at the bottom. Some weeks are a real adventure in fridge Tetris! And for Blizzcon, I’m probably gonna be stacking things extra tight just to fit it all, or even making use of my cooler + ice packs from Thursday night into Friday morning. . .
But in the end, this is what makes me happy and keeps us both fed and reasonably healthy, so I make it work :)
