Tiger Nuts (Chufa): what every chef needs to know
Tiger nuts are, despite the misleading name, not true nuts. They are small, dried tubers (rhizomes) of a grass-like plant from the Cyperaceae family. They are triangular to oval in shape, have a wrinkled brown surface and a sweet, lightly nutty flavour with notes of almond and coconut. The name "tiger nut" refers to the tiger-print-like grooves on the outer surface of the dried tuber. Botanically tiger nuts are not tree nuts and contain none of the nut proteins that cause EU-14 allergens in people with tree nut allergy. EFSA has assigned no tree nut allergen status to chufa. Tiger nuts are therefore a remarkable option for menu presentations where a nutty flavour is desired but guests with tree nut allergy can also enjoy the dish. Horchata de chufa is the best-known preparation: a traditional Valencian drink (PDO-protected as Horchata de Valencia) made from soaked and ground tiger nuts with water and sugar. This is the only plant-based drink with EU PDO protection in this category. The fat profile of tiger nuts is remarkable: 73% of the fatty acids consist of oleic acid (the same as in olive oil). The fibre content is high (33% of dry weight), with a beneficial effect on gut motility and satiety.

Tiger Nuts (Chufa): preparation techniques
Exact temperatures and times for HACCP compliance. Core temperature is leading for poultry and pork.
Soak dry tiger nuts in cold water for 24–48 hours. Change the water daily. After soaking, the tiger nuts are soft, sweeter, and suitable for eating as a snack or processing into horchata.
Blend soaked tiger nuts with water (ratio 1:3), allow to steep for 30 minutes, strain through a fine sieve or cheesecloth. Add sugar and a pinch of cinnamon. Serve cold. The traditional Valencian method uses a stone mill rather than a blender.
Spread dried tiger nuts on a baking tray and roast at 180°C until crunchy and golden brown. Sprinkle with salt, cinnamon, or chilli for varied flavour profiles. Cool before serving.
Grind dried tiger nuts to a fine flour in a powerful blender or food processor. Tiger nut flour gives a light sweetness and nutty flavour to gluten-free biscuits and cakes. Replace 20–30% of the flour base.

Frequently asked questions about Tiger Nuts (Chufa)
Are tiger nuts safe for people with a nut allergy?
Yes, tiger nuts are botanically not tree nuts. They are tubers of the grass-like plant Cyperus esculentus and contain none of the proteins that cause EU-14 nut allergens (almonds, hazelnuts, walnuts, etc.). EFSA has assigned no nut allergen status to chufa. However: always check the allergen certificate from the supplier for cross-contamination with tree nuts in the production chain.
What is horchata de chufa and how does it differ from other plant milks?

It is the only plant-based drink with EU PDO protection. Flavour profile: sweet, nutty, comparable to almond milk but without tree nut allergens. Nutritional value differs from other plant milks: less protein, more fibre.
How long do dried tiger nuts need to soak before use?
Dried tiger nuts need 24–48 hours to fully rehydrate in cold water. Shorter soaking gives harder, less sweet tiger nuts. After 48 hours they are soft, sweet and aromatic.

- Determining allergens in the finished product based on current supplier documentation;
- Maintaining and documenting a demonstrable HACCP management system;
- Controlling cross-contamination risks within their own production environment;
- Compliance with local food safety authority requirements.
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;
- Processing or preparation in your own kitchen that introduces new allergens.
Always verify allergens against the current specification sheets (spec sheets) from your supplier. Orally or informally provided allergen information is not legally valid under EU Reg. 1169/2011.
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.
