Unwrapped Caramels

Ingredients

Directions

The book gives no oven temperature. The 285°F in the steps was added when the recipe was transcribed, as a starting point.

Cook the syrup

  1. Boil the sugar, glucose, and water until it reaches weak crack stage (285°F).

  2. Remove the pan from the heat.

Finish and set

  1. Add the butter and milk, stirring gently until dissolved.

  2. Add the vanilla flavoring just before finishing the stirring.

  3. Pour into a greased pan to cool.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

White sugar
Provides the sweet base and, once cooked, the firm body of the caramel.
Glucose
Interferes with sugar crystals, keeping the caramel smooth and less grainy.
Butter
Adds fat for a soft, tender texture and rich flavor.
Condensed milk or sweet cream
Adds milk solids for creaminess and gentle browning during cooking.

The step that matters

Boiling to weak crack stage (285°F). The final sugar concentration set by the cooking temperature determines whether the caramel turns out soft and chewy or hard. Stopping too early leaves it soft, while cooking too far makes it brittle.
