Boil ribs, simmer these for 45 min. Let cool. Sauce: Mean will mix together.
When the meat is cooked, put in a big dish, (I use two, If you have no covers, cover with plastic wrap) Add the sauce and mix well to cover every piece of rib. Cover. Let marinate 8 to 24 hours. (I know it's long but...) They can be cooked on the Bbq. But I'm sure also in the oven. Bbq cooking time is 25-30 min.
I don't know where you are in Canada, but I'm in Quebec and (not to get any jealous reactions) but our Bbq is closed in, there is a window I can open, we Bbq all year round.
