What popular cooking ingredient ruins everything attaches. Ruin is a strong word, but a little truffle oil goes a long way. Also, blue cheese, blue cheese. For me, oregano. Tastes like decay. Black tuna. Can't stand it, capers, my wife's hands, fucking. Fennel, olives. Everything it touches tastes burnt garlic is death to a dish, avocado. It's in so many dishes but it adds no flavor. Only a god-of-all-slimey texture that ruins everything else on the plate. Bananas. Salon tro-a-k-a-quoryander. X-200-b-y would anyone do that? Barbeque sauce. Coconut. Oregano. A little is for color. My brother put a ton of oregano in our stew beef my grandma had started cooking. Ruined it. It was a sad day.
