Its not an exact science, but essentially, you dice one huge onion, sautee in oil, until its collapsed, add 1 lb of broiled chicken liver, cut up into pieces the size of a grape, add sugar and paprika to taste (there’s probably a touch of salt and pepper as well, but I’m not sure).
Best bet? Buy a small container from a take-out place, so you know what to aim for. Or stop by, if you’re in the area!
