Speaking of garlic chili paste, I'm looking for aji amarillo paste, which seems to be a requirement for numerous recipes in the Nobu cookbook. Essentially, I suppose it's the same thing, but I'd still like to try and find it. So far I haven't been succesful, although it took be forever to find yuzu juice - was always sold out where I went, or just generally non existent. Finally I prevailed - maybe aji amarillo paste will fall within my grasp as well. Any ideas on where to find it? I too would be eternally grateful.
