A Dish Like That, With Sparrows. Take clean walnuts, boil in water until overdone and strain the water from them. Clean sparrows [or: small birds] and put in a pot with that water, and throw on them oil, honey, onion juice, pepper and salt until done. Cover the greater part of it with ground ginger and galingale, and cut with musk, and use, God willing.
