Notes

Use a gentle simmer rather than a rolling boil to keep the broth clear and reduce splashing.

Kosher salt is optional because soy sauce and broth already contribute saltiness.

Let leftovers cool briefly, then refrigerate in a covered container within 2 hours.

Serving suggestions

Serve hot as a light lunch or dinner.

Pair with steamed jasmine rice for a more filling meal.
