I used to do a 1 to 1 oil/flour ratio of 96 ounces of stock. Over the years, I have increased that ratio to 1 to 1.75 or 2 (i.e.. 1 cup of oil to 1.75/2 of flour).

At 1 gallon of stock, I would use 1.25 oil to 2.5/3cups of flour.

1 cup of flour + 1 cup of fat is standard for a gallon of gumbo, but I like mine a little thicker so I add an extra 1/4 cup of flour.

John Folse and Judy Walker usually do a 9:1 ratio of stock to flour. I’ve seen folks go as thick as 6:1, I usually wind up closer to 12:1.

I use about 1 cup oil/flour to a gallon of stock. However, I use a lot of trinity, for a gallon of gumbo, ill have about 2 med onion, a bell pepper and 3 stalls celery.

1 cup of oil and 1 cup of flour yields 1 1/3 cup of roux, with a little oil left over.

From a survey of my large Louisiana cookbook collection, the liquid to roux ratios go from 20-to-1 all the way down to 6-to-1.

A gallon of liquid is 16 cups, but that does not account for the meat or vegetables in the pot, just the liquid that you put in.



I guess maybe I ought to work on the Gumbo Calculator some more.

Keep adding until you like the consistency. There's no set number. I cooked a gumbo for 70 people. I don't know how much water was in pot. I didn't measure it. I filled the pot halfway and started with 6 cups of homemade roux.

Keep in mind that the roux's ability to thicken decreases as the roux gets darker.

If I recall correctly, the Paul Prudhomme recipe that I model most of my gumbos on is 1/2 cup flour, 1/2 cup oil, and around 5 to 6 cups of stock.

When Stadium Rat makes gumbo, what’s his ratio?

When I make gumbo I do 1 3/4 cup fat to 2 cups flour, 5 quarts stock which is 160oz. I also add roughly 6lbs of chicken and 4lbs of sausage.
It can feed about 20 people, or give my family of four 3-4 days of leftovers (the best part).

I like mine a tad thicker than what most use, so I do almost 1.5 cups flour for a gallon of stock.

I start with 5 healing tablespoons of roux per gallon of water/stock. let that incorporate and add more as necessary to reach desired level of thickness
