Dark Chocolate Truffles

Melt chocolate with oil and the water. Stir in vanilla and sea salt. Transfer to an 8-inch square baking dish, and refrigerate until mixture is set but still pliable, about 2 hours.

With a 1-inch ice-cream scoop, make 28 balls, transferring each one to a parchment-lined baking sheet. Coat hands in cocoa, and roll balls to make smooth. Refrigerate on sheet 10 minutes. (Truffles can be refrigerated in an airtight container up to 2 weeks; let stand at room temperature 30 minutes before coating.) To serve, roll in cocoa or pat with nuts or coconut.
