Peanut Brittle
From a handwritten 'What's cookin'' card (antique cast-iron stove design). Attributed in the 'Recipe from the kitchen of' line to a Reatha Beard (confirmed by another card from her in the collection).
Ingredients
2 cups sugar ¼ cup water 1 cup white Karo (light corn syrup) Pinch salt ½ tsp vanilla 1½ cups raw peanuts 1 Tbsp butter 2 tsp baking soda Butter, to grease the cookie sheet
Instructions
1. Butter a cookie sheet generously and set aside. 2. In a saucepan, combine the sugar, water, white Karo, salt, and vanilla. 3. Cook to the brittle stage — about 300°F on a candy thermometer. 4. Add the raw peanuts and the 1 Tbsp butter. 5. Cook, stirring constantly, until light brown in color. 6. Add the 2 tsp baking soda and stir quickly — the candy will foam up. 7. Immediately pour onto the buttered cookie sheet, spreading thin. 8. Cool completely, then break into pieces.
Notes
Marye's card groups the sugar, water, Karo, salt, and vanilla together with a bracket and "cook to brittle stage 300°" — they're the candy syrup base. The peanuts, butter, and soda are added in sequence after the syrup hits temperature.
