This recipe worked for me. Two changes I had to make were using Karo instead of agave (didn't have it) and I had to stir the mixture for 4 minutes until it was nutty and dark. But it came out great and the family was thrilled.
Didn't work My carmel topping wouldn't stay on the apple. I think the agave made it too runny. Otherwise they would have been great. Pros: tastes great Cons: carmel is too thin and runs off
