Chestnut pavé is molded in a block shape like the paving stones that once lined the streets of Paris. For serving, it is sliced thinly and topped with whipped cream.
Lightly grease the loaf pan, line the base with wax paper, and grease the paper. If using fresh chestnuts, peel them, and put them in a saucepan with the vanilla bean, if using. Add enough water to cover, cover the pan and simmer until the nuts are tender, 25-30 minutes.
