Place corn curls in large roaster pan.
In a 2 quart saucepan, cook together for 2 minutes: 1 c. brown sugar 1/2 c. light corn syrup
Add 1 teaspoon baking soda to mixture. This will cause mixture to foam - so 2 quart saucepan is necessary. Pour caramel mixture over corn curls and stir until mixed. Place in 250 degree oven for 45 minutes. Stir at least every 10- 15 minutes. Remove from oven and pour on wax paper and break apart.
