The last time I was in Seattle, I went into Fran's Chocolates and sampled these amazing
gray salt caramels. I tried to recreate something similar here using himilayan pink sea salt. The recipe I used for the caramel is from the book
"Chocolates and Confections at Home". 
The recipe doesn't specify exactly what degree to cook the caramel at and just tells you to test it out with a spoon. For the caramel that I made, I ended up cooking it till about 246F and it was a good consistency. It held its shape but was still soft enough to chew on.

1 tsp salt (I used 2 tsp)
-lightly butter a 9x13" baking pan
-combine water, sugar, vanilla bean, condensed milk, butter, and corn syrup in a pot and bring to a boil, stirring constantly. Mixture will foam so be sure you use a fairly large pot.
