re: Onions and hot dog technique in crawfish boils.

I peel and score the onions and they go in right after the seasoning and the lemon, right before the garlic and potatoes, so right after i light the burner.

I can't remember doing hot dogs myself but I add smoked sausage at flameout, loose, and let it soak with the crawfish. I also add the artichoke at this time. I do not add ice to the water so they soak 20-30 minutes in hot water.
