My mom makes fantastic candy. Especially her brittle and toffee. I have never been able to master it. She is very good knowing what stage the candy is at based on the "cold water test" (drop a little in cold water and depending on how it solidifies, she can tell if it is soft ball, soft crack, hard crack, etc.). I never could tell... not really.
This last visit I had an AH-HA! moment and decided to write down the temperatures on the candy thermometer for the different steps (I know. Duh, huh?). That was all it took!
I have since made peanut brittle and english toffee both on my own and both were delicious! Now my Mom won't be forced to make a double batch for me every time we visit. :)
