In a double boiler over hot water, place peanut butter to heat while preparing syrup.
In a large saucepan combine sugar, corn syrup, and 1/4 cup of the water.
Cook over high heat to 275 degrees on a candy thermometer.
Lower heat to medium, add butter, stirring until melted.
Add peanuts, cook stirring for about 5 minutes until candy starts turning brown and reaches 300 degrees on the thermometer.
Remove from heat, stir in baking soda that has been dissolved in a teaspoon of water.
Add vanilla.
Working quickly, fold in the warmed peanut butter, while stirring gently. At once, pour candy mixture onto a well-greased marble slab or a cookie sheet. Very quickly...spread as thin as possible! The secret of the candy is quick cooling. When cold ...break into serving-size pieces.
