How to make brittles
Espresso Brittle
1/3 cup espresso beans
1 1/2 cups sugar
3/4 cup light corn syrup
1/2 cup water
3 Tbsp unsalted butter, cut into pieces
Preheat an oven to 350 degrees F. Place the espresso beans on a baking
sheet and toast them for 8 to 10 minutes.
Let cool, then crack them by placing them in a plastic bag and hitting
them with a mallet. Cover the kitchen counter with aluminum foil and
lightly oil the foil. Spread the cracked espresso beans evenly over the
foil.
In a medium sized heavy saucepan, combine the sugar, syrup and water and
bring the mixture to a boil, stirring until the sugar dissolves.
Continue to boil until the mixture becomes amber in color.
Remove from heat, stir in the butter, and pour the mixture evenly over
the beans. Allow brittle to cool for one minute. Use an oiled rolling
pin to flatten the mixture to about 1/8". Let cool, then break into
irregular pieces. Store in a tightly closed container.
