Tom Colicchio’s always like “you didn’t develop any flavor” on Top Chef and most people are probably like “what’s he talking about?” My quick answer is: “He’s talking about making things brown.”
Generally speaking, when you’re cooking something, you want it to turn brown (or, to use a prettier word, you want it to “caramelize.”) What that really comes down to is taking things further than you might otherwise feel comfortable. The hard part is if you take them too far, there’s no going back. So you’ve gotta get in there, hover over the pan, but don’t hover too much–if you stare, you’ll be tempted to stir, and that stops the browning. It’s a delicate dance, developing flavor, but if you do it the right way you can create a dish that’s way more dynamic than it has any right to be–like this dish of spaghetti with crispy chickpeas and preserved lemon.
