Peel shallot, dice finely, steam in butter. Add to the wild garlic, puree together with the milk either in the mixer or with the knife of the hand mixer.
In the meantime, heat the cream and dissolve the squeezed gelatine in it. Add to the pureed mass, mix briefly, pour through a fine sieve.
Stir in the sour cream, season with salt and pepper.
Divide into four small glasses, let set for at least four hours, but preferably overnight.
