Not knocking Mikes and understanding $79+ for one Key Lime pie = delivery but I can use Nellie and Joe’s recipe and make 20 pies for that.  Mike’s must really be some GOOD pie.
So, in answer to the question, Key Lime pie.  I don’t like super sweet stuff.

I Don’t pay that price. On another thread about Receiving Christmas goodies stated that two sons ate one of my pies in transport. LOL
His recipe is on the internet for the pie. But find the Carrot Cake Recipe I have from them. Wifes favorite.
Believe retail around $24.00, locally. Not bad.
