I've used a similar shortbread recipe for years...but this is even better! I won't go back. Kosher salt doesn't always mean the coarsest salt ever. The brand I used worked fine; dissolved. I used 1/2 the salt because I only had salted butter. I've never buttered, Pam-ed, greased, oiled shortbread pans. There's far too much butter in the mixture to call for the pans to be treated, in my experience. Parchment paper could be helpful for those with pans that want to stick anyway. I used a round enamel-ware quiche pan and the wedges baked beautifully. Thank you for this recipe. It's on my gifting list to family and friends for Christmas.
I used a pie plate sprayed with butter-flavor cooking spray instead of a cake pan and reduced the cooking time to 20 min. Tried it the first time as is, then tried a couple of variations-substituted ground pecans for part of the flour and sprinkled the top with chopped pecans, and another version adding toasted almonds. All three were awesome!
Please add to this recipe to line the pan with parchment paper. the taste is good when you pry it out of a non-stick pan already sprayed with PAM
