Clean the beans, wash them and cook them for about 5 minutes in boiling salted water. Then rinse with cold water and drain. Meanwhile, clean and wash the peppers and cut them lengthwise into narrow strips. Peel the shallots. Blanch the peppers and shallots briefly in boiling water, rinse with cold water and also drain.
Peel garlic and cut into thin slices. Clean, seed and wash the peppers and cut them into thin rings. Fill beans, yellow and red pepper strips and shallots in portions into the prepared glasses, so that they reach up to approx. 2 cm below the rim. Bring vinegar, 1/8 litre water, sugar, 1 tablespoon salt, garlic and chilli peppers to the boil and fill into the glasses so that the vegetables are completely covered. Place the rubber rings and lid on the cleaned edges of the glass and keep them moist. Close the preserving jars with hangers or springs, making sure that the rubber rings do not move. Fill a deep baking tray about 2 cm high with hot water. Place preserving jars in the baking tray and cover the jars with a damp cloth. Push the tray onto the lowest rail of the preheated oven (electric oven: 175 °C/ gas: level 2). As soon as the liquid bubbles in the glasses (bubbles rise), measure the boiling time for 80 minutes.
