* Maria Crackers (Galletas Marias) are a round sweet biscuit with vanilla flavor. They are the Mexican version of the English Marie biscuit and can be used in layered deserts as you would with lady fingers. They can easily be substituted with graham crackers. **Piloncillo is often used in Mexican cuisine to sweeten drinks or deserts. It is unrefined cane sugar, usually found in the shape of small cones and can be substituted with brown sugar.
