When my daughter was growing up, her school used to have candy sales to raise money for supplies needed in the classroom. The mothers were asked to donate. I had a favorite recipe for peanut butter fudge that I always sent. It was a hit then, and it is still a hit as I always make it – by request – for Christmas gifts.
In a saucepan, combine the sugar, syrup, salt, milk, and water. Bring mixture to a boil, cover, and cook 2 minutes. Uncover and cook without stirring until a little of the mixture dropped in cold water forms a soft ball (232 degrees on a candy thermometer). Remove from heat. Cool to lukewarm (110 degrees). Add peanut butter and the vanilla. Beat until mixture thickens and loses its gloss. Pour into a buttered 8x8x2-inch pan. Cool.
