Grandma's Christmas Brittle Recipe

This came from the Tase of home site, and man is it great. I thought this would be a good place to keep it safe.

Ingredients

• 3  cups sugar
• 1⁄2 cup light corn syrup
• 1  cup water

Directions

1. Grease two baking sheets and keep warm in a 200° oven. In a large saucepan, combine the sugar, corn syrup and 1 cup water. Cook over medium heat, stirring constantly, until a candy thermometer reaches 240° (soft-ball stage). Stir in butter, salt and peanuts. Continue heating, stirring constantly, until the mixture reaches 300°.
