I discovered that the stick blender is awesome for smoothies
The one I have here may be commercial grade or something, I don't know. It's on semi-perma-borrow status from my partner's chef brother. It is very powerful though, and my son made a great smoothie the other day with unsweetened yogurt drink/kefir, fresh strawberries, and chunks of ghiradelli white chocolate. It was delicious, although I thought it would be too liquid for me. I usually only like them made of all frozen ingredients, so thick that a normal blender can barely handle them and a straw would be pointless.
Do stick blenders normally grind plum seeds to nothing in a short time? I really don't know if this one is 'normal' or not, kind of curious...
