I always wanted to make these, and finally got the guts — oh boy, I wasn't really prepared for the amount of nitty-gritty with making these. I started with original German recipe that called for 500g of almonds, but that ended up being 2 full baking sheets and lots of sneaky snacking between steps ;-) But the result is good, and these cookies are worth the effort.
Tuna paste is ridiculously easy to prepare and makes a great no cooking bento, cutting the preparation time to less than 20 minutes, including rice cooking time! Now, that's what I would call cooking on the go! You can also use the tuna paste for a great tasting onigiri or sushi.
