I love nuts, so I've made lots of nut pastes and pralinés with mine. Walnut praliné is amazing with a touch of salt.
I also made a pecan praliné, but that felt like a bit of waste of good nuts, doesn't really do it. Can't remember if I did it 50/50 or 60/40, but would mos def go with 60/40 if I tried again.
