Mushroom smørrebrød is one that has found new life at modern smørrebrød restaurants, where it has become a signature dish at places like Aamanns. The mushrooms are sautéed quickly over high heat so they get colour and flavour instead of stewing in their own liquid — that is the key technique here. The hazelnut cream gives a nutty, earthy base that suits the mushrooms’ umami, and the pickled red onions add sweetness and acidity. This is an autumn smørrebrød at its best with fresh wild mushrooms like chanterelles and porcini, but it also works well with good button mushrooms.
