I made a syrup from ground black walnut and sunflower seeds, but boy is it overly sweet. I do know I could use some form of flour (qinoa, amaranth, millet, all purpose, corn meal, corn starch, etc), but I’m curious if anyone might know of something I haven’t thought of yet.
Butter, or some other type of fat like coconut oil would probably help.
You could also try pectin.
