Crystallized Caramel
Your caramel turned grainy because sugar crystallized. Dissolve the crystals and re-cook with a little acid to keep it smooth.
Ingredients on hand
- crystallized caramel
- water
- lemon juice
- saucepan
- pastry brush
Why it happened
Sugar crystals form when stray grains seed the syrup or when it is stirred too much. Acid breaks sucrose into glucose and fructose, which resist crystallization and keep the caramel smooth.
The fix
- 1 add 1/4 cup water and heat over medium, swirling until the crystals dissolve completely
- 2 add 1/4 teaspoon lemon juice and boil without stirring until the caramel turns amber
- 3 wash down the pan sides with a wet pastry brush to prevent new crystals
If it's still wrong
- Let it harden, crush it, and use as a crunchy topping for ice cream or yogurt.
- Stir the grainy caramel into hot coffee or tea where it will dissolve.
Prevent next time
- Use a clean, dry pan and avoid stirring once the syrup boils.
- Brush down the sides of the pan with water as it cooks.
- Add a small amount of acid or corn syrup at the start.
Notes
Why this works
Caramel starts as a solution of sucrose in water. If a few crystals survive on the pan wall or you stir too much, those crystals act as seeds and trigger a chain reaction where the whole batch crystallizes.
Adding water re-dissolves the crystals so you can reset the syrup. Acid converts some sucrose into glucose and fructose (invert sugar). These molecules interrupt the crystal lattice, making it much harder for sugar to re-form into a grainy mass.
Substitutions
- lemon juice → cream of tartar (1/8 teaspoon)
- water → coffee for a mocha caramel
