Bought a bottle of Slap ya Mama. Now what?

I’d bet my life there’s a recipe on the bottle.

“Slap Ya Mama Etouffe Sauce”

Wouldn’t make gumbo with that, if that’s your plan. For etouffe knock yourself out.

FWIW, make your own “jarred” roux in the oven. It’s foolproof and will last forever in fridge. 2:1 flour to oil, 400F stir every 15 min until you get it as dark as you want it. Let it cool, jar, refrigerate. Done. Add to boiling stock stirring until incorporated. Proceed from there.

Get you a jar of this, some leg quarters, a good smoked sausage and go with it. Your friends and family will say, "damn baw, where'd you larn to cook like this?"

Depending on how much effort, time and ingredients you've got to give, you can do anything from what's on the jar, which will come out fine, to what Tigre ^^ above said which is sort of "doctoring it up" a bit which will come out even better while also helping to stretch that jar out further.
