Peanut Brittle - Grandma's was the best!

1 1/2 cups white sugar
2/3 cup Karo syrup
2/3 cup hot water
2 cups raw peanuts
3 Tbsp butter
1/4 tsp salt
1 Tbsp vanilla
1/2 Tbsp baking soda dissolved in 1/2 Tbsp water


Combine sugar, Karo syrup and water in a saucepan.  Cook over medium high heat stirring until dissolved.  Cover and cook 3 minutes.  Remove lid and cook until it makes a brittle ball in cold water.  Add peanuts, butter and salt and cook until it again makes a brittle ball in cold water.  Stir this constantly.  When finished add the vanilla and baking soda in water.  Mix thoroughly and spread very thinly on greased sheet or parchment paper. Once it's cooled break into large pieces and store in an airtight container.
