No smoker needed. These are wrapped in foil and slow-cooked in a camp oven for an hour and a half at low coal heat, then opened and crisped for twenty to thirty minutes with more coals on the lid. The foil traps steam, which is what makes them tender.
How long should the ribs marinate?
One to two hours minimum in the fridge, with overnight being ideal. The marinade is two tablespoons of soy sauce mixed with about half a cup of the honey glaze. Coat them thoroughly, then pour half the marinade into the foil parcel and keep the rest for glazing.
Should I take the membrane off spare ribs?
Yes. Slide a knife under the silvery membrane on the back, grip it with paper towel and pull it off in one strip. Left on it stays chewy, removed the ribs are tender. Pat the ribs dry afterwards before they go into the marinade.
