Note from Ricardo The homemade marshmallows can be replaced by 18 store-bought marshmallows. The hot chocolate with marshmallows on a stick will keep for 1 week in an airtight container in the refrigerator. Remove the skewers, as needed. Let the cubes of hot chocolate reach room temperature before adding them to hot milk. For an original gift idea, wrap the hot chocolate with marshmallows on a stick in a decorative box.
