Just a few helpful hint to the people that is having trouble making peanut brittle and other home made candy. If it is not crounchy and brittle and is soft like and sticks to your teeth, It may be 3 things. 1st I was always told by my mother never make candy on a rainy day. It will not harden properly and over the years I have found that to be true. But being the person that never does what I am told. I soon found out if I need to make candy on a rainy day I can cook it about a min. longer and it comes out fine.
2nd- brittle will not harden properly if the baking soda has been setting open for a long period of time It will loose its stringth.
3rd- the brittle was not cooked long enought. Always make sure that it will string a thread. That is the best way to know if it is done.
I hope this will help you.
