You can crush the garlic with the garlic press.
If you got pine nuts, you can mash them up either with a mortar and pestle or even by putting them on the cutting board and using a rolling pin to roll over them.
If you got walnuts, use the nut grinder (glass jar bottom, plastic cup top with metal teeth and small crank) to grind them up.
Dump the ingredients in order into the plastic tub. Stir them up good. If the mixture isn't very moist, or if it's most but gritty, add some more oil, one T at a time, until it has a fairly smooth consistency, but you don't want the stuff to be swimming in the oil.
