  2. Boil the mixture for about 25 minutes, stirring occasionally.

  3. The mixture should be soft and not too brittle.

Set and cut

  2. Use a knife to mark the caramels deeply before they cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Grated chocolate
Adds deep flavor and color, and firms the caramel as it cools.
Yellow sugar
Provides sweetness and, as it dissolves and heats, helps form the caramel's body.
New orleans molasses
Adds moisture, a chewy texture, and a rich, slightly bitter depth.
Milk
Adds creaminess and softens the texture of the caramel.
Butter
Adds fat for a smooth, tender texture and richer flavor.

The step that matters

Boil for about 25 minutes, then check the texture. Sugar mixtures set harder the longer they cook, because more water evaporates and the sugar concentration rises. Stopping at the right point keeps the caramel soft rather than brittle, and stirring prevents scorching on the bottom of the pot.
