Hi Matt, I have made this recipe 3 or more times and yes the garlic turns sort of bluish and I'm still alive, it's a chemical reaction and it's safe to eat. I used a mix of cayenne, rocotillo, aji, habanero and jalapenos that I had dried along with my garlic that I grew also, wow, it is really good. I use those small freezer containers and froze individual containers of it because I didn't know how long it would last in the frig, turns out not long at all since we eat it up so quickly. Anyway here is a site that has some information about pickling peppers and garlic. http://www.ext.colostate.edu/pubs/foodnut/09314.html Karen in SC > turned blue. Is this a problem?

Does anyone else have thoughts on > this? > > Thanks. > > Matt >
