For your viewing pleasure and inspiration.
Vlaai is a typical Dutch pastry which just so happens to fit really well in a 10" cast iron skillet. Super easy to make and with the cast iron it doesn’t stick to the pan. Serve with a generous amount of whipped cream and coarse sugar.
Found the Limburger
Limburgse vlaaien are delicious though
