Everyone had great ideas and I will be using each one. The one for tomorrow night is taken from littleknitter's recommendation of Fillets en Papilotte. I am making Halibut en Papilotte, with roasted leeks and fennel first in, topped with halibut and a little crab and a cream sauce. How far ahead do you think I prepare them before popping in the oven? 6 hours? 3 hours? 1 hour? The base recipe is from Cookwise.
(Oh, and $10 off your order of $50 or more in the Food52 Shop, too.)
