Years ago, I had a deliciious southern pie that had a bit of a crunch/bite on the top layer--not like a creme brulee, more delicate. I've since tried various buttermilk pie and sugar pie recipes, but none had quite the same texture in either the top or the filling. Ideas? I remember the filling as soft, creamy, not overly sweet and utterly delicious. Not much to go on, I know, but I'm willing to try all ideas!
