Pecans are perhaps most well known in the US for their use in pecan pie and pralines. However, they have a variety of other delicious applications, from sweet to savory.
For dessert & breakfast applications, add pecans to waffles, pancakes, sticky buns, cheesecake, quick breads, muffins, cakes (especially carrot cake), pies, candies (especially caramel, chocolate or nougat based), ice cream, brownies, etc.
Pair pecans with flavors like vanilla beans, chocolate, butter & browned butter, nutmeg, maple syrup or maple sugar, brown sugar, orange, goat cheese, berries, stone fruit, mascarpone, bananas, rum, pumpkin, cinnamon, molasses, winter squash (especially kabocha), sweet potatoes, pork, or other nuts.
Pecans are delicious finely chopped and mixed into unsalted butter with honey or maple syrup to make a sweet compound butter (how to make compound butter).
To awaken their full, intensely buttery flavor, briefly toast pecans in single layer in a 350˚F oven until hot & aromatic. Nuts scorch easily, so be sure to check on them frequently and shake the pan periodically to redistribute them and promote even toasting.
