Pralines were originally created in France by coating almonds in caramelized sugar. The praline got its name from French soldier and sugar industrialist, Marshal du Plessis-Praslin, as it was his cook who invented it.
The recipe evolved when French settlers brought the recipe to Louisiana where chefs in New Orleans eventually substituted pecans for almonds and added cream.
Pralines now come in many flavors and include several different types of nuts. It's no wonder they have their own day. Happy National Pralines Day!
