Method

1. 1

   The roux is the dish, and the color is the dial

   Flour cooked in fat browns through blond, peanut butter, milk chocolate and finally the color of an old copper penny, and each stage tastes different. Dark roux is nutty, smoky and deeply savoury, and it thickens far less than a pale one because the starch has been broken down by the heat. That is the trade you are making: flavour for body. A dark roux gumbo is thin and intensely flavoured, and thickening it with more flour afterwards defeats the point.

2. 2

   Equal parts by volume, a heavy pot, and medium heat

   Three quarters of a cup of flour to three quarters of a cup of oil, whisked together in a heavy-bottomed Dutch oven or a cast-iron pot over medium. A thin pan gives you hot spots and hot spots give you black specks, which taste burnt and cannot be picked out. Use a neutral oil with a high smoke point rather than butter, which contains milk solids that scorch, or olive oil, which is not stable enough for forty minutes at this temperature.

3. 3

   Forty minutes, and you cannot leave the stove

   Whisk or stir constantly with a flat-edged wooden spoon that reaches the corners, keeping the whole surface of the pot moving. It will look like nothing is happening for fifteen minutes and then change quickly, so pay closer attention as it darkens. Have the diced vegetables sitting beside you before you start, because when it hits the color you want you have about ten seconds to act. If black flecks appear, throw it out and start again, since there is no rescuing a burnt roux.

4. 4

   The trinity goes in hot and stops the roux dead

   Onion, green bell pepper and celery, roughly two parts onion to one each of the others, all diced small and added straight into the roux at temperature. It will hiss violently and the pot will drop about a hundred degrees, which is exactly what you want, since it arrests the browning before it goes too far. Stir for five minutes until the onions go translucent, then the garlic for one more minute.

5. 5

   Warm stock, a ladle at a time, or the roux seizes

   Cold liquid hitting hot roux makes it clump into lumps that will not disperse no matter how long you simmer. Simmer the shrimp shells in the stock for twenty minutes first, strain, and keep it warm on the next burner. Add it to the pot two ladles at a time, stirring each addition until smooth before the next goes in. After the first three or four additions the mixture is loose enough that you can pour the rest in steadily.

6. 6

   Chicken first, sausage second, shrimp in the last five minutes

   Add the chicken thighs, bay, thyme, cayenne and paprika and simmer uncovered for forty-five minutes, then lift the thighs out, pull the meat and return it. Add the andouille and simmer another thirty minutes, which is enough for its fat and spice to move into the broth. The shrimp go in for the final four to five minutes only, off a gentle simmer. Shrimp added at the start are rubber by the time the gumbo is ready, and that is not recoverable.

7. 7

   File or okra, and never both at once

   Both are thickeners and they do the same job differently. Okra is added with the trinity and cooks down over the whole simmer, giving a slightly viscous body and a green vegetal note. File powder, which is ground sassafras leaf, goes in off the heat at the very end and gives a silky texture and a faint root-beer aroma. Boiling file makes it stringy and unpleasant. Using both is a Louisiana argument you do not need to have on a weeknight.

8. 8

   Skim the fat, and season at the end because the andouille moves

   Let the pot sit off the heat for ten minutes and skim the orange fat that rises, which is normal and is where most of the greasiness complaints come from. Only now taste for salt, because a pound of andouille can add anywhere between 400 and 900mg of sodium a serving depending on the brand and you cannot predict it. Add the file powder, the scallions and the parsley, and a splash of vinegar or hot sauce if it needs lifting.

9. 9

   Rice in the bowl, gumbo over it

   Cook the rice separately and mound about half a cup in the bottom of each warmed bowl, then ladle the gumbo around and over it. Rice cooked in the pot absorbs the broth, breaks down, and turns the whole thing into a stodgy casserole by the second day. Kept separate, the gumbo stays a broth and the leftovers reheat properly. This is also why gumbo is better on day two while jambalaya is not.
