Pistachio Brittle

Steps

• 1

  Heat oven to 200°F. Grease 2 cookie sheets. In heavy 5- to 6-quart saucepan, place sugar, corn syrup and water. Heat to boiling over medium heat, stirring frequently. Stir in butter.
• 2

  Cook over medium heat, stirring occasionally for about 10 minutes until candy thermometer reaches 240°F. Meanwhile, place cookie sheets in oven. (Warm cookie sheets allow the candy to spread easily before it sets up.)
• 3

  Stir pistachios into sugar mixture; continue cooking, stirring frequently, until candy thermometer reaches 300°F. Remove from heat; stir in baking soda (mixture will be light and foamy).

  Remove cookie sheets from oven; pour candy onto cookie sheets. With buttered spatula, spread until candy is about 1/4-inch thick. Cool completely, about 1 hour. Break into pieces. Store in tightly covered container.
