Description
Lactarius resimus is a prized conditionally edible mushroom, especially popular in the Slavic culinary tradition for salting. It grows in birch and birch-spruce forests, forming mycorrhiza with elm.
Its hallmark is the thick white milk that oozes when the flesh is damaged. The mushroom is conditionally edible: fresh, it is acrid and bitter, and fit to eat only after prolonged soaking (2–3 days, changing the water) or salting.
The gold standard for cold salting: fermented milk caps take on a crunchy texture and a piquant, tangy, sour-milk flavor.
Cap
Cap 8–20 cm across, convex or flat in young mushrooms, then funnel-shaped. The surface is smooth or slightly sticky, white or creamy white, and may have yellowish concentric zones. The margin is inrolled and fluffy, fringed with white hairs — a hallmark of the species.
Hymenophore
Gills crowded, narrow, decurrent, white or cream. When damaged they release abundant white milk that doesn't change color in the air (unlike some related species). The bitter milk is the reason soaking is a must.
Stem
Stem 3–7 cm tall, 2–4 cm thick, firm, solid (hollow in old mushrooms), cylindrical or narrowing toward the base. White or slightly yellowish in color, smooth. No ring and no volva.
Flesh
Flesh firm, brittle, white. When damaged it releases plenty of white, hot milk with a very acrid taste. After proper soaking or salting, the acridity disappears completely.
Smell
Smell fresh, pleasant, slightly fruity or with notes of fresh flour. The characteristic “milk cap” aroma, familiar to anyone who has ever salted them — unobtrusive and pleasant even when raw.
