Love making gumbo and love making roux - kind of a like a rite of passage

But I love going to restaurants that have a really dark and thick roux

I can get my roux to a dark chocolate color but when i add the trinity/roux to the boiling water and chicken stock, it always seems to lighten up and thin out

It tastes great, but other than adding a corn starch slurry, how do you darken and thicken the roux?

I use either bacon fat or veg oil for the fat and a 1:1 ratio with flour

Use a little less fat to flour in your ratio and make more roux than you usually do. Add it until you get the consistency you want. I like my gumbo to have body, but I don't want a stew.

My roux usually darkens a bit more when I add the trinity to saute. However, the roux stock mixture lightens up a bit because you're diluting the roux. I still get the dark roux flavor, though.

Thank you

Would you go with a 1:1.25 of oil:Flour ratio?

Sure. You can experiment until you get what you're looking for.

My buddy's wife helped me figure it out. She went wild on the flour. At least 1.5 : 1, maybe almost 2:1 flour to vegetable oil ratio, playing with the burner frequently. Needless to say, the roux was thicc

Whats your process? Do you make a roux and add the trinity to the hot roux?

When I do it that way I always go to 1:1, so the oil can can coat cook my trinity.

I always found that the gumbo darkens the longer you simmer it. Not sure if there is any merit in that, but that is my experience. My roux usually looks like dark chocolate when I add my trinity for reference.

The darker the roux, the less thickening power. So, you need more roux. Never tried changing the flour/oil ratio. I'll have to try that next time. Also, thought about making a dark roux and then adding blond roux later to thicken.

yes - make the roux, then add the trinity - One thing could be to reduce the water/broth too

Obviously adding stock will lighten the color up too, but adding water as opposed to just a homemade stock will affect it a good bit as well I’d imagine.

For gumbo, the roux doesn't need to thicken it a lot. Not like we're making an etouffee here.

For dark, there are two components, roux and stock. The roux is easy, brown it longer. I make my own stock. Browning the bones first gives a better flavor, less grease and darkens the stock.

For thickness, two options, more roux or less stock. That's about it

And okra. It’ll thicken it up a bit as well.

ETA: Is okra not a natural thickener? Am I missing something with these downvotes?

I love to fry my own chicken and will do so about once every other month. I have a fair sized cast iron pot that can easily hold half the cut up chicken to fry.

When I'm done, I let the oil cool overnight so any coating settles and I drain and strain the oil, clean the pot and add the oil back into the pot then get it up to temperature to start adding flour. When it's the consistency I want I let it start to brown and stir it constantly with the wire whisk or roux paddle I use to move it in the pot. Average time to make my roux this way is 45 minutes-------or 2 cold beers.

When done, I let it cool enough to be able to put it in Mason jars to store in the fridge till needed. I usually wind up with 1 full quart and 1 full pint jar.

That's so much easier than making a roux every time I need one by having it on hand when needed.

My roux color is as dark as a Hershey Chocolate Bar.

To make darker

1. Cheat ... Kitchen Bouquet
2. Sorta Cheat...Caramelized tomato paste...in a small skillet heat a thin layer of oil to shimmering then squiggle in a trail of tomato paste and stir until deep brown with a spatula... it's fast. Stir browned sauce into gumbo while simmering. The degree of browning increases with simmering time.

This will take longer but try the oven method. 1.5 flour to fat ratio. It’s almost impossible to burn and you can take it very very dark. Also, like someone else mentioned, make a lot more roux the darker you go.
