En1gma Have you experimented with other nuts? Almonds, work well Pecans, quite frankly pecan anything is just incredible. Pistachios have too low an oil content so need a lot of oil added (I burned out a blender motor trying to make butter without adding oil. The colour is a bit odd (the green/brown mix is well...), but I've just made a batch with good olive oil added and it's worth a try. Cashew, again too dry without added oil and I was a bit disappointed in the taste.
If vegetarians eat vegetables... What do humanitarians eat?
