As you can see in the picture, this bacon is just about ready to be removed from the heat.

bubbly bacon

Just what are those bubbles/foam(?) on the surface of the bacon?

Note: this is fresh bacon from a butcher-- not processed or packaged-- if that makes a difference.

I'm pretty sure that's just steam and hot air bubbling in the layer of fat/grease that's all over the bacon.

  • yep it's boiling water, and the oil in the pan is rendered fat. the same way whale blubber was rendered into lamp oil. Just an interesting factotem
