This season's "hot" and hip ingredient. Ghost pepper salt?

It sounds obvious but I love it any place you'd use both salt and hot sauce: eggs, veggie & rice bowls, chicken or burgers.

What about salt brownies, carmel corn or mango toffee

i bought some from the spice and tea exchange, its fantastic. I don't think it's all THAT hot, but it has nice heat. I add it to Asparagus along with a smoked salt after tossing with olive oil and bake at 375 to preference. I'll also add it as a finish to eggs and skirt steak sammies. mmmm

I imagine you probably don't have a huge quantity of it, but it sounds like it would make an interesting (and friggin hot) curing salt. Maybe cure some egg yolks since you don't need much for that..? Then you could use those to grate over dishes.
Honestly, I would probably just use it as a finishing salt for steaks and fish. Or maybe add it to scrambled/poached/fried eggs to really wake my ass up in the morning.

On the pastry side of things, it would be a fun ingredient to play around with on, say, chocolate truffles/bonbons or on ice cream.

You can make your own. I purchase ghost chilies from Alvarez Brothers here in Washington State. Dehydrate them and grind them and mix with whatever.

I have some ghost chili salt and it is terrific. I like to scatter a small pinch over my finished dishes like tomato salad, Mac and cheese. Would probably taste great very lightly sprinkled over chowder and tomato soup.
