Clean, wash and cut the beans into pieces. Cook in boiling salted water with 2 stems of savory for about 15 minutes. Cut the sausage into slices. Wash, clean and slice the tomatoes.
Wash and quarter the pears and remove the core. Cut pears crosswise into medium-thick slices. Wash the remaining savory. Pluck leaves except for something to garnish. Drain the beans.
Heat clarified butter in a large frying pan. Fry the sausage briefly. Swirl pears and tomatoes in the fat. Add beans, savory and stock. Cook for about 10 minutes at low heat.
Season with salt and coloured pepper. Serve with crème fraîche and garnish with the remaining savory. Fresh baguette tastes good with it.
