Treacle Toffee

Ingredients

Directions

  1. In a saucepan, melt butter over medium heat.

  2. Add treacle and let it boil gently.

  3. Test by dropping a small portion into cold water; it should break between your teeth.

  4. Once ready, remove from heat immediately to avoid burning.

  5. Pour onto a buttered dish and let cool.

  6. Once cool, roll into sticks and wrap in clean white paper.

  7. If desired, flavor with peppermint, almond, lemon, or add a pinch of cayenne pepper.
