Peel the shallots and cut into thin slices. Wash the thyme, shake dry and chop up to 4 stems for garnishing. Mix 3 tablespoons vinegar, salt, pepper and 1 pinch of sugar. Fold in the oil.
Stir in thyme and shallots.
Dice the ham. Wash the cucumber, remove the seeds and dice finely. Mix with the ham. Fold 6 rings (approx. 4 cm high; approx. 8 cm Ø) from aluminium foil and put them on plates. Pour in the ham tartar and press it in a little.
Heat a good 1 1/2 l water, 100 ml vinegar and 1 slightly heaped tablespoon of salt in a wide saucepan until it is just before boiling. Beat the eggs one by one into a cup or soup ladle. Slide carefully into the vinegar water and leave to stand for about 4 minutes.
Carefully remove aluminium foil from the tartar. Spread vinaigrette over it. Lift out the eggs with a skimmer, drain and arrange on the tartar. Garnish with thyme. Delicious with baguette.
