I like to purchase bacon in the large package and prefer the thick sliced. If I don't freeze it, it will not hold the flavor until I use it all.
When we have company, I just take out extra and fry it in the frying pan.

If you want to freeze bacon without it sticking together in a clump, roll each piece from one end to the other like a jellyroll. Place each rolled piece, side by side, and lay flat in ziplock bag in freezer.
