Boil eggs in boiling water for about 10 minutes until hard. Clean the cauliflower and cut it into florets from the stalk. Blanch in boiling salted water for about 3 minutes. Drain and immediately rinse in ice water.
Quench the eggs, peel and chop them. For the vinaigrette, whisk vinegar, salt, pepper and honey. Add oil drop by drop. Wash the dill, shake dry and roughly chop the tips. Peel shallot and cut into fine cubes.
Stir the dill and shallot into the vinaigrette. Clean, wash and dry purslane. Clean, wash and slice the radishes. Mix the eggs, purslane, cauliflower and radishes, arrange and sprinkle with vinaigrette.
