The @cookbookbookclub is back at it again, and with our #CookItinCastIron cookbook in hand, they’ve served up a batch of our Drop #Doughnuts. The excellent heat retention of cast iron makes it the ideal vessel for frying, since it can keep the oil nice and hot, so we naturally turned to our 12-inch cast iron skillet during recipe development. Share with us what you’re cooking in cast iron in the comments below, and to pick up your own copy of #CookItinCastIron, click the link in our bio!
