I can't offer you any tips for the caramel- that was all Ken. But he pulled if off without a candy thermometer, so if you're gutsy, give it a try! (It wasn't really all that difficult from what I can tell ;) And it was GOOD!
You can also just buy caramel at a store and warm it up.
So, here's what you do:
1. Put the caramel in a mug and put the mug in a pot of water on the stove at a low temperature (enough to get it all melty).
2. Dip the pretzels, let the excess run off into the mug, then lay flat on parchment paper to cool. (Caution: supervise & help your young kids if you have them helping with this part- it gets HOT!)
3. Repeat steps 1 & 2 for the chocolate, with the pretzels that already have caramel on them.
4. You're done! (Well, you can swirl white or coloured chocolate on top, or sprinkle on nuts or crushed candy canes or whatever you like while the chocolate is still soft, if you have time & want to get fancy :)
They're so good!
