Here's a favorite recipe of mine. Makes 1 kilogram of high-density solid jet fuel.
200 grams walnuts
200 grams almonds
100 grams cashews
100 grams sesame seeds
100 grams sunflower seeds
(need it be said, all raw and unsalted?)
200 grams dried fruit (raisins, apricots, prunes etc., of the unsulfured variety)
50ml canola/safflower oil
100 grams whey protein
A pinch of salt, if you want
Blend all nuts and sunflower seeds in a food processor or large blender until they are finely chopped. Add raisins, oil and finally protein powder and salt, and blend until you've got one hell of a goopy mess...I mean, until everything is thoroughly mixed. Stir in sesame seeds, then roll the resulting goop into balls, cylinders, obelisks, whatever.
Keep them in the fridge until you need them.
Caution: they're sticky and oily, but damn, they're good!
