Piloncillo

Store in an airtight container in a cool, dry place. It may become harder over time, but this does not affect its quality. You can grate it if it becomes too hard to break.

To soften hardened piloncillo, place it in a sealed container with a slice of bread or an apple wedge for a day or two.

Grate hardened piloncillo using a microplane or cheese grater for easier dissolving.

Use piloncillo to add depth of flavor to marinades, rubs, and sauces, not just sweets.

Assuming it will dissolve as easily as refined sugar; it takes longer to melt.

Not storing it properly, leading to excess hardening.
