Onions peel and cut into slices. Put them in a pot with bacon, 1/2 teaspoon salt, peppercorns and about 1 1/2 litres of water and bring to the boil. Cover and simmer gently over medium heat for about 45 minutes.
Peel, wash and chop the potatoes. Add the potatoes to the bacon about 20 minutes before the end of the cooking time. Remove the outer leaves from the savoy cabbage. Cut cabbage into slices, cut out hard stalk.
Cut cabbage into pieces and wash. Wash oregano, dab dry, put something aside for garnishing. Tie the rest with kitchen string to a bunch. 7-8 minutes before the end of the cooking time, add the savoy cabbage to the potatoes.
Wash and quarter the pears, remove the core, cut the flesh into slices and sprinkle with lemon juice. Remove oregano and bacon. Stir starch with a little water until smooth, bind the simmering stock with it until slightly creamy, bring to the boil again, add pear wedges and leave to stand for about 5 minutes.
Cut the bacon into pieces, put them back into the pot, season with a little salt, pepper and a little sugar. Serve and garnish with remaining oregano. Crème fraîche tastes good with it.
