I have heard about this dish from my friend but I have never tasted it. Fern salad is that strange combination? She said it delicious though. Now I want to try it. And share with you the recipe of fern salad. So I found one. But still you should remember that not all fern you can eat, some kinds of them are toxic. And it is better to buy it in the special markets.
In general all ingredients are simple. For four person you will need, 1/2 cup white wine vinegar, 2 teaspoons salt, 1/2 cup vegetable oil, 2 teaspoons sugar, fresh herbs, 1/2 cup onion, 2 teaspoons garlic and about 230 gram of edible fern. This is all for salad. In addition you need prepare souse and garnish.
For souse you will need about 230 gram of beets, you'd better buy it in can with liquid, 1 tablespoon red wine vinegar, 1 tablespoon onion powder, 1 hot chili pepper and salt. And very few products for garnish it is 1/2 cup of mushrooms and 8 small sprigs lovage or parsley.
Preparing is quite complicated, two days
