Not sure how you like your ribs, I've found that steaming them before slow cooking on the BBQ works well.
In the oven in a pan, with a rack, water under the rack and ribs on top, and a lemon or two in the water. Cover with foil and bake 45 mins 350degF
Now that I have a multicooker (like an Instant Pot, but it's a Breville) I do the same thing, except it only takes 20 minutes. Then either cook on the BBQ or store in the freezer (I use a vacuum sealer).
