Solteritas are thin, crisp orange cookies fried on a flower-shaped iron and served with a sweet cream of the same colour. They are the Colombian version of the Scandinavian rosette, and they need the mold: the iron is heated in the oil, dipped in the batter and returned to the oil. Makes about 30.
You need a rosette iron for this recipe: a flower-shaped metal head on a long handle, sold in Latin stores as a molde para solteritas and in the US as a rosette iron, where it is used for Scandinavian Christmas rosettes. There is no workaround. Never grease the iron: it sounds helpful and makes the batter slide off.
