Castagne alla valdostana is a traditional appetizer originating from the Aosta Valley. This sweet appetizer is usually made with a combination of chestnuts, butter, honey, grappa, and salt. The chestnuts are soaked in warm water overnight and cooked in boiling salted water.

They're cooked and glazed over low heat in a mixture of butter, grappa, and honey. This appetizer is served warm and it's typically accompanied by a platter of local cheeses and mixed cold cuts. The chestnuts can also be served with more syrup as a dessert in a cup, accompanied by whipped cream.
