Jerusalem artichoke is native to North America. Nicknamed the artichoke of Jerusalem, this vegetable has been completely forgotten for years. It must be said that during the Second World War, Jerusalem artichoke was consumed in large quantities. Of course, this did not leave good memories for the Europeans who turned away as soon as possible. However, this root vegetable, available all winter long, needs to be known.

It contains carbohydrates of the fructan family: inulin and oligofructose. These contribute to the balance and diversity of our intestinal flora which is, among other things, responsible for our immune defenses. It also contains iron, vitamin B1, vitamin B5, phosphorus, potassium.
Problem: When the inulin of Jerusalem artichoke ferments under the action of intestinal bacteria, a large amount of gas is produced. This is then evacuated as flatulence. So as not to be spared, we go soft on quantities.
