Fry a glass of nuts (seeds) at a temperature of 200 ° C for 5 minutes. (I was frying in the microwave in the “Aero” mode) and grind into very fine crumbs with a blender. If there is no blender, pass it through a meat grinder with a fine mesh.
Nuts can be packed more tightly in a glass (so that there is less empty space in it).
