Considering your dental issues, maybe grind raw nuts or seeds and soften the butter then mix the two. Or a TINY amount of raw honey as well, just enough to sweeten it.
Or warm some meats very gently, then melt the butter over it.
Or grind the nuts to near powder. then coat the tiny pieces of meat with the butter, then roll in the nut powder.
The last one will have to be an experiment, have never tried it, but I'm just brainstorming here with ways to use it without being able to chew much or at all.
Will think more. Good luck, hope you get some more, and creative replies!
