The following is a formula much used by German canary-bird raisers:
Sweet almonds, blanched......... 16 parts
Pea meal........... 32 parts
Butter, fresh (unsalted)........... 3 parts
Honey, quantity sufficient to make a stiff paste. The ingredients are worked into a stiff paste, which is pressed through a colander or large sieve to granulate the mass. Some add to every 5 pounds, 10 or 15 grains of saffron and the yolks of 2 eggs.
