Mix the coriander, honey, onion, cider and
vinegar in a large bowl (not a metal one).
Add the quails and marinate overnight.
Preheat the oven to 180oC/350oF/Gas
Mark 4.
Drain and reserve the marinade. Dry the
quails with absorbent kitchen paper.
Heat the butter and oil in a large
casserole. Add the quails, 4 at a time, seasoning them with salt and
black pepper. Brown on both sides.
Put all the birds in the casserole and
pour the marinade over them. Cover and cook in the oven for 40-45
minutes, basting occasionally, or until tender.
