crunchy caramel bark
from vanillasugarblog.com

caramel filling:

1/2 cup water 
1 cup white sugar
1 & ½ TB light corn syrup
Giant pinch of sea salt, optional 
1 cup heavy cream

In a sturdy/heavy medium size saucepan, over medium-high heat, heat up the water, corn syrup, sugar and salt. Stir once or twice to make sure it’s combined, that's it, no more stirring. You will cook this for at least 10 minutes (maybe longer) until it turns a nice golden brown. Once it starts to turn brown, do not leave the stove because it turns dark brown very fast. Swirl the pan, once or twice, that's it to confirm color is a nice golden brown, once it is, take off heat and add in the heavy cream. Let it bubble up and do its thing, then stir sauce with a heat proof spatula or whisk, and keep stirring till you get it combined and thickens a bit.

Put off to the side or in a heat-proof glass measuring cup (easy for pouring later) to let cool.

If all went well you should have a fairly thick, pourable caramel. Let this cool at least an hour before using.

Bark:
2 sleeves of Ritz crackers (50 crackers? More or less)
1 cup of roasted pecans (I used roasted and salted pecans)
16 ounces of milk chocolate: melted in 2 batches; 8 ounces each

Line a jelly roll pan with parchment paper. Lay down an even layer of Ritz crackers; add more crackers to cover up any gaps. All gaps need to be covered as the caramel will ooze out.
Take the cooled caramel and pour over the crackers. You probably won’t use all the caramel; I didn’t, so save the remainder for another use.
Place pan in fridge to chill and set up for at least 2 hours.
When set up melt about 8 ounces of chocolate in a double boiler, spread the chocolate over the cracker and caramel. Let cool and harden at room temp for about 20 minutes then into fridge for an hour.
Take out of fridge, and being careful, flip the mixture over exposing the other side. This side will now get covered in chocolate.
Melt the remaining milk chocolate, spread over the bark and then sprinkle on the roasted pecans. Push the pecans down into the chocolate a bit to make sure they stay.
Let this harden for at least a couple hours before slicing. Use a sharp knife to cut this so the caramel doesn’t ooze out.
