How can you make you peanut brittle harden?

Question

I've tryied to diiferent recipes and I can't get either of them to harden. I need help.

Answer 1

When the temperature reaches 300 degrees remove the pan from the heat immediately. You may do this at 290 degrees, if the desired level of brownness has been reached. Do not let it go above 300 degrees, or the finished product may develop a weak, spongy structure. Immediately after removing the pan from the heat, add the butter and vanilla extract, and stir (carefully-it's HOT ! )until the butter is melted. Sprinkle the baking soda over the surface of the mixture and stir. The mixture will begin to foam up and double in volume. Now you need a clean, smooth, flat surface to pour the mixture onto. A marble pastry board is ideal, as the marble allows the candy to cool slowly enough so you have time to stretch it before it hardens. You may use a large baking sheet, but you will have to work quickly because the candy will cool and harden more rapidly. Prepare the surface ahead of time by coating it with butter or non-stick cooking spray. Immediately after stirring in the baking soda, pour the hot mixture onto the surface.

Answer 2

You achieve this by adding the soda after you take it off the heat.

1 cup light corn syrup
1 cup granulated sugar
1 tablespoon butter
1/4 teaspoon salt
raw peanuts (however many you like)
1 heaping teaspoon baking soda

put all the ingredients, except the peanuts and soda, in a deep sauce pan. Put on medium heat. stirring constantly until sugar dissolves. Now add the peanuts. Stirring at all times, take mixture to 290 on a candy thermometer. Remove from heat and stir in one heaping teaspoon baking soda (make sure baking soda is fresh). Now pour out on a greased cookie sheet. do not tip cookie sheet to thin, this peanut brittle is best when thick which makes it more airy.

Answer 3

make sure it is at brittle stage with a candy thermometer before you shut it off and pour it
