Timing is everything and in few places does it matter as
much as in cooking. Underdone, overdone, or perfectly done is all a
result of timing. It's a basic that often gets overlooked in the
process of chopping, marinating, basting, and otherwise agonizing
over a meal. Freshness of ingredients also matters. How long should
you keep the stock you made over the weekend? How long does it take
to defrost the turkey?
