About Water pepper
Water pepper is the pungent leaf of an edible knotweed-family plant, used as a fresh herb or seasoning. The leaves may be chopped into dishes or used to add sharpness to sauces and other preparations. They are narrow, pointed, and green, with a distinctive peppery bite rather than the flavor of black peppercorns.
Fresh leaves have a biting, pepper-like heat and a green, slightly bitter quality; drying changes their aroma and intensity. The ingredient may be sold fresh or dried, and the name can refer to other plants in some contexts. This record denotes the herb called water pepper, not a ground pepper spice.
