Chestnut purée

Preheat oven to 400 degrees F.

Roasting the chestnuts

Using a strong, sharp paring knife, cut an X into the flat side of each chestnut shell. This will allow the steam to escape, preventing the chestnuts from bursting and making them easier to peel. Place chestnuts in a single layer on a baking pan. Roast for 15 to 20 minutes, stirring halfway through. Chestnuts will be roasted when shells begin to peel back. Remove chestnuts from oven and let stand for five minutes to cool. Peel the shells and skin away from the nuts.

In a saucepan, combine chestnuts, sugar and water, bringing the liquid to a boil. Reduce heat to medium-low and simmer for 25-35 minutes, until the majority of the liquid has evaporated. Remove from heat and stir in vanilla. Strain chestnuts, reserving sugar syrup, and transfer to a food processor and blend until smooth. Add in syrup slowly until desired consistency is obtained. Allow to cool before refrigerating. Makes approximately two cups.
