Jerusalem Artichoke / Sunchoke: what every chef needs to know
Stock your walk-in with Jerusalem Artichoke / Sunchoke — a knobbly tuber of an American sunflower species. The name "Jerusalem artichoke" is a corruption: the plant has nothing to do with Jerusalem and is botanically not an artichoke, but has a comparable flavour with its inulin content. Inulin is a prebiotic fructo-oligosaccharide that is not digested by humans but is fermented by gut bacteria. In large portions inulin can cause flatulence. Jerusalem artichoke has a nutty, lightly sweet flavour that is best expressed when roasted and puréed. Rich source of potassium and vitamin C. The skin is thinner than potato skin and can be eaten.

Frequently asked questions about Jerusalem Artichoke / Sunchoke
Why is it called a Jerusalem artichoke?
"Jerusalem" is a corruption of "girasole" (Italian for sunflower); "artichoke" refers to the comparable flavour due to the inulin content. The tuber therefore has nothing to do with Jerusalem and is botanically not an artichoke.
How do I reduce the flatulence from Jerusalem artichoke?
Use smaller portions (max 150g per person). Prolonged cooking (above 100°C/212°F) breaks down some of the inulin. Combining with fennel seed or caraway can also help. Eating it regularly allows the system to adapt.
Do I need to peel Jerusalem artichoke?
Not necessary: the thin skin is edible and contains extra nutrients and flavour. Scrubbing under cold running water is sufficient. For purées or fine preparations, peel with a vegetable peeler. Oxidation: place immediately in lemon water after peeling.

Allergen information: Limitations
The allergen information on this page relates to the ingredient as such. The actual allergen composition of your purchase may differ due to:
- Varying suppliers, production facilities or growing regions;
- Cross-contact during production, transport or storage ("may contain");
- Changed product formulations not yet reflected in public sources;

Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
