This month's Maxim has a great tip to keep your bacon from curling:
Before cooking, run the strips under cold water and they won't curl up in the pan. Perfect for sandwiches. And arterial clogging!
I ran this past Chef and this is a known 'trade-secret'. So, if you're in the mood for a bacon sammich (and who isn't?!), here ya go.
And one more thing while we're at it: Quit buying cheap bacon. Get ya some applewood smoked bacon – you'll thank me later.
