Caspiroleta is a hot Colombian drink of milk, chocolate, egg and bread, boiled and whisked until frothy. The egg cooks in the boiling milk, and the bread dissolves into it, which makes the drink dense enough to be a light meal. It is what Colombians make for someone who needs building up. Serves four.
If you have no molinillo, a regular whisk or a hand blender works. Whisk from the moment everything goes into the pot, not just at the end: that is what keeps the egg smooth and builds the froth.
