Cassava: what every chef needs to know
There has earned its reputation — a reason Cassava shows up on so many prep lists: it is a root vegetable from South America now one of the most important carbohydrate sources for over 800 million people worldwide in tropical and subtropical regions. The root has a brown, fibrous outer skin and white, starch-rich flesh. Cassava has two main varieties: sweet cassava (low cyanide content) and bitter cassava (high cyanide content). The critical food safety aspect of cassava is the presence of cyanogenic glycosides, above all linamarin and lotaustraline. When the root is cut or damaged, these compounds are converted by the enzyme linamarase into hydrogen cyanide (HCN). Bitter cassava can contain up to 1,000mg HCN per kilogram. Sweet cassava contains 20–30mg HCN per kilogram. Codex Alimentarius STAN 238-2003 sets a maximum of 10mg HCN per kilogram in cassava flour. Preparation is absolutely mandatory: cassava must always be peeled, soaked (8–24 hours) and/or cooked to a core temperature of at least 100°C (212°F) for 10 minutes to fully deactivate HCN through thermal and aqueous extraction.

Cassava: preparation techniques
Exact temperatures and times for HACCP compliance. Core temperature is leading for poultry and pork.
peel cassave completely, remove the houtige core, cut in pieces and boil in generous salted water minimum 20-30 minutes to completely cooked. pour kookwater weg (contains uitgeloogd HCN). never raw consumeren.
boil cassave first completely cooked (voorkoken required). let cool, cut in staven and frituur in twee stappen: first 160°C (3 min) for the core, than 185°C (2 min) for crispy exterior. serve directly.
boil cassave cooked, pour af and stamp while the still warm is in a mortar of with a stamper. add no water to: the stijfheid of fufu requires that the vocht in the cassave itself gebruikt is. traditional served at stews.

Frequently asked questions about Cassava
Is cassava poisonous and how do I make it safe?
Raw cassava contains cyanogenic glycosides that convert to hydrogen cyanide (HCN) when processed. To make cassava safe: peel completely, remove the woody core, soak for 8–24 hours in cold water (changing the water every 8 hours) and boil for at least 20–30 minutes to a core temperature of 100°C (212°F). Always discard the cooking water.
What is the difference between cassava and tapioca?
Cassava is the fresh root vegetable. Tapioca is purified starch extracted from cassava, free of cyanogenic glycosides through an industrial washing process. Cassava flour retains fibres and flavour; tapioca starch is virtually pure starch (99% carbohydrates). Tapioca pearls are extruded tapioca starch.
How do I recognise sweet versus bitter cassava?
In supermarkets in the Netherlands, virtually only sweet cassava (Manihot esculenta var. dulcis) is available with an HCN content of 20–30mg/kg. Bitter cassava (much higher HCN) is rarely sold fresh in Europe. Visually they are difficult to distinguish: mandatory preparation applies to both varieties at all times.
How do I make the best yuca fries?
Peel and fully cook cassava first (20–30 minutes). Allow to cool and cut into batons. Fry in two stages: first at 160°C (320°F) for 3 minutes to cook through the centre, then at 185°C (365°F) for 2 minutes for a crispy exterior. Season immediately with sea salt and serve with aioli or chimichurri.
At what temperature should you store Cassava?
Store Cassava at Rauw: room temperature max 1-2 days after oogst; cooked: 0-4°C, compliant with EU Regulation 852/2004 and Codex Alimentarius guidelines.
How do you prepare Cassava professionally?
The primary professional technique for Cassava is Boiling at 100°C for 20-30 min. Always verify core temperature with a calibrated probe thermometer.

Under EU Regulation 1169/2011 (Food Information Regulation) and EU Regulation 852/2004 (HACCP Hygiene Regulation), the Food Business Operator (FBO) is solely and exclusively responsible for:
- Providing accurate, up-to-date and complete allergen information to the end consumer;
- 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.

- Allergic reactions, food poisoning or other health incidents involving guests or staff;
