Wash the mountain lentils and place them in unsalted water. Cook for 20 - 25 minutes. Wash the red lentils and boil them once in unsalted water. Drain both types of lentils and set aside.
Blanch the tomatoes, peel, remove seeds and roughly chop the flesh.
Peel carrots and celery, cut both and the washed leek into fine cubes and sauté gently in olive oil. Dice the tin white bread and fry in olive oil to make croutons. Mix balsamic vinegar, chicken stock, olive oil with salt, sugar and pepper to make a vinaigrette.
Pluck the thyme.
Add the lentils to the vinaigrette and mix with the diced vegetables, tomato and croutons. Leave to stand for a while, then add plucked thyme. Salt a little water lightly, bring to the boil, add marjoram, parsley, unpeeled shallots and garlic, as well as the allspice seeds and let the black puddings steep for about 10 - 15 minutes.
In winter, instead of fresh tomatoes, it is better to use chopped canned tomato flesh.
