This is a pretty unique and food-centric group. I always felt to a certain degree what you keep in your icebox is a reflection of who you are…at least culinarily.
Three things that are almost always in my fridge?
Kewpie Mayonaise ~ the ultimate for dressing sandwiches.
Simple syrup that I make and keep on hand for iced tea. I can’t believe people actually buy this!
Kretchmer Honey Crunch Wheat Germ. I sprinkle it on lots of stuff, not the least of which is peanut butter toast.
Lardo, Guanciale, Pancetta and other assorted cured meats
Sambal
Fish Sauce
Duck/Goose Fat
Veal Demiglace
Various Stocks
Bone Marrow
Badoit
Anchovy Paste
