Minestrone at 80 ºC / 176ºF

Minestrone is a speciality of Italian cuisine. The most common ingredients are beans, onions, celery, carrots and tomatoes (all finely chopped). But there is no set recipe for the preparation of minestrone, because typical seasonal vegetables are normally used and this depends on the area where it is made. Some pasta or rice is often added. It may be a purely vegetable soup or, conversely, it may contain meat or meat-based ingredients such as chicken stock, pork fat and ham, among others.

When cooked in a vacuum bag, there is no loss of water. Cooked in a pan, on the other hand, the water will gradually evaporate. By cooking while sealed, the juices are concentrated in the bag and the flavour will be more intense.
