Wash 1 cup of chestnuts, then in a large pot, put them to boil with plenty of water.
Boil for 50 minutes, then drain, and peel them with a paring knife. Remove the outer shell and the thin brown skin under the outer shell. Don't worry if they break, we'll blend them in a second.
Blend all the ingredients together until you have a smooth cream. You can make the cream more or less smooth based on your preference. We like it smooth but with a grainy texture.
Serve as a pesto dressing for a delicious pasta, or as a spread on some toasted bread for a delicious and healthy breakfast.
