Chocolate Caramels

Ingredients

Directions

The book gives no oven temperature. The 240°F in the steps was added when the recipe was transcribed, as a starting point.

Cook the caramel

In a saucepan, combine sugar, molasses, milk, and butter.
Heat over medium heat, stirring until the mixture comes to a boil.
Continue boiling until it reaches the soft ball stage (about 240°F or 115°C).

Finish and set

Remove from heat and stir in the chocolate until melted and smooth.
Pour into a greased pan and let cool before cutting into squares.

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

What each ingredient does

Sugar: Sweetens the candy and, as it cooks, builds the caramel flavour.
Molasses: Adds deep flavour and moisture, and keeps the caramel softer.
Milk: Adds moisture and milk solids for a creamy, chewy texture.
Butter: Adds fat for a smooth, tender texture and richer flavour.
Chocolate: Adds chocolate flavour and fat, making the candy richer and smoother.

The step that matters

Boil to the soft ball stage (about 240°F or 115°C). Cooking drives off water and concentrates the sugar, which sets how firm the caramel becomes as it cools. Stopping early leaves it sticky and soft, while going too far makes it hard and brittle.
