doesn't seem to have this added, but the caramel mixture is about the same temperature. I would like to try the coffee toffee posted at SmittenKitchen or the one Orangette posted, but I'm a bit worried that it would be too hard on the teeth. I'm thinking of using my brittle recipe, and making toffee with it. I noticed that the Almond Roca recipe that Meryl posted has the baking soda added. I think I will use that recipe as my guide. any thoughts on soda/no soda?
