How do I stop my fish from curling when frying?

Chef's answer
You can sear them skin side down then when you turn them over gently poach them. With how small they sound the entire cooking process should only be about two to three minutes long at most. Not even getting that far. I put them in the pan skin-side down, but they're curling immediately.

Most of the time, bacon will come out flat and browned and beautiful just like that. If you have particularly thin or fatty pieces of bacon, however, it can still curl up on you as the water evaporates from the meat and the belly fat renders.
