Peanut Brittle
Ingredients
Directions
Make the brittle
Melt the sugar over gentle heat.
Stir constantly when the sugar begins to bubble at the edges until fully melted.
Hold the pan high above the flame to let the last few lumps disappear; the liquid should be amber colored.
Add the baking soda and mix thoroughly, then add the chopped nuts.
Pour the mixture onto a moistened bread board.
Shape and cut
When slightly cool, turn the edges up into the center and roll to ½ inch thick.
Cut into squares.

What each ingredient does
- Sugar
- Melts and caramelizes to form the brittle's hard, amber, sweet candy base.
- Baking soda
- Reacts with the hot sugar syrup, releasing gas that makes the brittle light and porous.
- Chopped nuts
- Add crunch and roasted flavor to the brittle matrix.
The step that matters
Holding the pan above the flame to clear the last lumps. Sugar that is undercooked stays soft and sticky, while overheated sugar turns bitter and dark. Watching for an even amber color shows the sugar has reached the right stage for a brittle that sets hard and crisp.
