Basic Miso Soup

The cardinal rule of miso soup: never boil the miso. Heat above a low simmer kills the live cultures in the paste and dulls the flavor. The recipe handles this correctly by pulling the pot off the burner before the dissolved miso goes in, then stirring it through. Anything hotter and you’ve cooked away the very thing that makes miso soup taste like miso soup.

Wakame needs its rib pulled. After a five-minute soak in cold water, the dried seaweed plumps into glossy green ribbons. Run your finger down the central spine of each piece and tear it away; that part stays tough no matter how long you cook it. The remaining tender flesh gets diced and added to the simmering broth.

Onion goes in first for a three-minute simmer to soften and sweeten. Carrot and wakame follow for another five. The whole thing comes together in under twenty minutes. Scallions on top right before serving keep their fresh bite.

Pro Tips

• Use white (shiro) miso for a milder, sweeter soup; red (aka) miso for a saltier, deeper version
• Dissolve the miso fully in a few tablespoons of warm broth before stirring it in to avoid clumps
• Make the broth more traditional by using dashi (kombu-and-bonito stock) instead of plain water
• Slurp it before the wakame absorbs too much liquid; reheats lose texture

Variations

• Stir in cubed silken tofu for a more substantial bowl
• Add sliced shiitake mushrooms with the carrots for an umami boost
• Drop in a handful of cooked soba noodles and a soft-boiled egg for a meal-sized version
