Hi. I have lived here quite awhile, and cook all the time, and have never seen almond butter. what living here does do for you, culinarily speaking, is force you to be resourceful and make things that you never made before. Almonds are really common, so just make your own!
You can buy sea salt in a dietetica, or a store like Jumbo. They don't sell coconut oil here, but you can buy sesame oil & peanut oil in Barrio Chino, or olive oils and your more generic processed seed oils in any supermarket. The recipes I saw use a food processor, but you can chop and grind your way to a decent almond butter if you're willing to be persistent (and don't want to buy a processor or a blender).
