I made a test batch of candy this week that was beyond awful. A co-worker makes it every year and it's totally trashy, but delicious. It should have been easy-Peanut butter, almond bark, rice crispies, marshmallows. Wellll, I didn't have almond bark, so I used white chocolate chips. This, apparently, does not work. They didn't melt to a liquid consistancy, just combined with the peanut butter to form a sort of doughy looking mixture. I also thought it would be a good idea to add some vanilla extract to cut down on the sweetness. This did not improve the texture at all. I decided to give it a shot anyway and dumped it over the cereal I substituted (rice chex, no marshmallows). This, apparently, does not work. It sort of mixed together, but not really and it was just a clumpy mess. Plus it just tasted funky, the white chips just didnt' taste all that good and totally overpowered the peanut butter.
After 41 years, you would think I would learn to not try to make my own substitutions!!!!!
