Wash the carp, dab dry and cut into approx. 5 cm wide slices. Sprinkle with lemon juice and salt. Clean or peel and wash the soup greens. Cut 2/3 into pieces, the rest into fine strips
Bring a good 2 l salted water, coarse soup vegetables, bay leaf, juniper, allspice and peppercorns to the boil in a wide pot. Cover and simmer for about 10 minutes. Crumble the cake and soak in beer
Let the carp steep in the stock at low heat for about 15 minutes. Carefully lift out and keep covered warm. Finely mash the cake and beer. Fill up with 400 ml fish stock, bring to the boil, simmer for about 15 minutes
Steam the vegetable strips in little boiling salted water for 3-5 minutes. Season the sauce to taste, beat butter into it. Arrange carp pieces with sauce and vegetable strips. Boiled potatoes taste good with it
