To actually cook things enough. I wasn’t cooking them to unsafe levels before, and please don’t cook my steak above medium rare, but some foods just taste better cooked more. Almost no one cooks ground meats enough, who the hell wants grey beef, get some color on that bitch. Also if you cook sausage meat enough it gains color and the flat renders out a little it tastes better. Get some colour on those roast veggies and no one likes a pale insipid fry. A change in color is flavor, use it to your advantage. And yes sometimes you want your veggies firm and for the love of god don’t overcook your garlic.
