Great ways with wild mushrooms: Horn of Plenty in a Mustard Vinaigrette

Horn of Plenty (also known as black chantarelle or black trompet; Craterellus cornucopioides in Latin) is a chanterelloid, or chanterelle-like, mushroom. It's very dark, almost black, making it a challenging mushroom to forage, as "it is like looking for black holes in the ground". Despite its rather unattractive appearance, it's a delicious and delicate mushroom that retains a good bite even after cooking.

I admit I didn't forage for these particular black trompet mushrooms (on the photo below) myself, but bought some at the Central Market in Tallinn. These shouldn't be too difficult to get hold of in other countries as well - I clearly remember buying some at a French deli in Edinburgh, and there are plenty of recipes using these mushrooms in both British and US food magazines (as compared to some other wild mushrooms I've mentioned over the years).

It's a quick recipe to throw together - but it needs to marinate overnight in the fridge. I loved the mustard flavour and the bite the mushrooms had. Great as a side dish to some meat, or on a slice of toasted light sourdough bread.

Serves 4



a large punnet (about 400 g/1 litre) of fresh horn of plenty mushrooms

Mustard vinaigrette:
4 Tbsp vegetable or olive oil
3 Tbsp strong sweet mustard
1 Tbsp wine vinegar
3 garlic cloves, finely chopped
0.5 tsp salt or 1 tsp sea salt flakes
0.5 tsp dried tarragon or 0.5 Tbsp fresh tarragon leaves
0.5 tsp fresh thyme leaves
freshly ground black pepper

Wipe the mushrooms clean. Place onto a hot dry frying pan and heat for about 3-5 minutes, until most of the mushroom 'juices' that emerges evaporates. Remove the mushrooms from the pan and let cool.
Combine the vinaigrette ingredients and spoon over the cool horn of plenty mushrooms. Give the mushrooms a good stir, then cover and leave to marinate overnight in the fridge.
