Method

  1. Prepare the yam and pepper blend

    Even white yam chunks beside a mostly smooth pepper blend for Nigerian yam pottage

    Peel 1.2 kg of white yam with a sturdy knife, cut it into even 4 cm (1 1/2 in) chunks, and rinse once in cool water. Remove the stems from 170 g of red bell pepper and 1 Scotch bonnet chile, then remove the seeds from 170 g of red bell pepper. Quarter 340 g of ripe tomatoes and 170 g of yellow onion. Put half of 170 g of yellow onion in a blender with 340 g of ripe tomatoes, 170 g of red bell pepper, 1 Scotch bonnet chile, and 120 ml of water for blending; blend until mostly smooth. After handling the chile, wash the knife, cutting board, and hands thoroughly and avoid touching your eyes.

  2. Cook the pepper base and start the yam

    Cooked red pepper and palm oil base with small oil beads before yam is added

    Warm 45 ml of red palm oil in a wide heavy pot over medium heat. Add the other half of 170 g of yellow onion and cook for 3 minutes, stirring, until the edges soften. Stir in the pepper blend, 1.5 g of dried thyme, 1 g of ground black pepper, and 5 g of fine sea salt. Cook uncovered for 8 to 10 minutes, stirring frequently, until the raw tomato smell fades and small beads of red oil appear at the surface; set the timer for the first check at 8 minutes. Add 1.2 kg of white yam and 720 ml of water for cooking, stir well, and bring to a steady boil.

  3. Simmer and thicken the pottage

    Partly mashed white yam thickening Nigerian yam pottage in a pot before greens are added

    Reduce the heat to medium-low and partially cover the pot. Simmer for 18 to 22 minutes, stirring gently every few minutes so the yam does not catch. Set the timer for 18 minutes, then check a center piece; a fork should slide in without resistance. Press about one-quarter of the softened yam chunks against the side of the pot with a wooden spoon, then stir the mash back through the sauce until it looks thick and spoonable while most chunks remain intact.

  4. Fold in the greens and finish

    Wilted spinach folded through thick Nigerian yam pottage in the cooking pot

    Add 200 g of fresh spinach in two additions, folding each batch into the hot pottage until it begins to wilt. Simmer uncovered for 3 to 4 minutes, stirring gently, until the greens are tender and the sauce still falls slowly from the spoon; set the timer for the first check at 3 minutes. Turn off the heat, taste, adjust the seasoning if needed, and let the pot stand for 5 minutes before serving immediately.

Cook's noteAim for a pottage that is thick enough to mound softly on a spoon but still has a little movement. Mash more yam for a smoother pot, or leave more chunks intact for a firmer texture.

Smart Substitutions

  • No fresh spinach? Use chopped ugu leaves when available, or use tender kale with the tough stems removed.
  • No red palm oil? Use a neutral cooking oil, knowing the pottage will lose some of its characteristic color and earthy flavor.
  • Need less heat? Use half of the Scotch bonnet chile and remove its inner ribs before blending.
  • No white yam? Use firm-fleshed sweet potato or cocoyam, but expect a sweeter flavor or a softer finished texture.

Tips and Variations

  • Cut the yam into similar-size chunks so the pieces soften at the same rate.
  • Stir gently once the yam is tender; vigorous stirring can turn every chunk into mash.
  • Add the greens only after the pottage has thickened so their moisture does not make the sauce watery.

What Went Wrong?

  • Pottage is too thin Mash a few more yam chunks and simmer uncovered for several minutes, stirring often.
  • Pottage is too thick Stir in a small splash of hot water until the sauce loosens without becoming soupy.
  • Yam is still firm Add a little hot water, partially cover the pot, and continue simmering until a fork slides through the center.
  • Pepper base tastes raw Cook it a few minutes longer before adding the yam, until the sharp tomato aroma softens and red oil shows at the surface.

FAQ

Is Nigerian white yam the same as sweet potato?No. Nigerian white yam is a starchier, firmer Dioscorea tuber with a dry, neutral flavor. An orange sweet potato will cook more quickly and make a sweeter, softer pottage.
