Chestnut Flour: what every chef needs to know
Chestnut flour is ground dried European chestnuts, one of the traditional flour types in use before the introduction of potatoes and maize to Europe. The flour has a rich, sweet flavour with pronounced chestnut notes and a light brown colour from the dried nuts. Chestnut flour is naturally gluten-free and has a higher sugar content than wheat flour (the sugars in chestnuts are sucrose and maltose), contributing to its characteristic sweet flavour. In commercial kitchens, chestnut flour is the base for castagnaccio, chestnut polenta and chestnut crêpes. The high sugar content makes chestnut flour suitable for sweet preparations but it burns faster at high temperatures from the Maillard reaction and caramelisation. Protein content (5.4g per 100g) is lower than wheat flour; chestnut flour forms no gluten network and always requires a binder (egg, xanthan gum) in baking. Chestnut flour turns rancid quickly because of its fat content (3.8g per 100g); store cool and dark, preferably refrigerated after opening.

Chestnut Flour: preparation techniques
Exact temperatures and times for HACCP compliance. Core temperature is leading for poultry and pork.
Mix chestnut flour with water to a yoghurt-consistency batter (1:1.5 ratio); pour into a greased, floured baking tin to 1 cm thickness; scatter rosemary, pine nuts and soaked raisins over the top before baking.
Blend chestnut flour with regular polenta in a 30:70 ratio for a less dominant chestnut flavour; stir continuously in salted water and finish with butter and mascarpone.
Use a blend of 50% chestnut flour and 50% rice flour for thin, crispy crepes; the high sugar content of chestnut flour causes rapid caramelisation, so use medium heat.

Frequently asked questions about Chestnut Flour
Can chestnut flour replace wheat flour in recipes?
Chestnut flour cannot replace wheat flour 1:1 because it contains no gluten and therefore forms no gluten network. In gluten-free recipes, chestnut flour works well combined with a binder (egg, xanthan gum) and other gluten-free flours. The sweet flavour makes it more suitable for sweet preparations than savoury dishes.
Is chestnut a nut allergen?
Chestnut (Castanea sativa) is not on the list of 14 major allergens in EU Annex II (Regulation 1169/2011). It is botanically not a nut but a fruit of the beech family. Cross-reactivity with tree pollen (birch pollen) is however possible in pollen allergy sufferers. Declare on the menu when in doubt.
How long does chestnut flour keep?
Unopened and stored dry, chestnut flour keeps for 12 months. After opening, refrigeration is recommended due to the high fat content that can turn rancid; shelf life after opening is then 3–4 months. Discard immediately if a rancid aroma develops.
At what temperature should you store Chestnut Flour?
Store Chestnut Flour at 4-10°C (refrigerator after opening due to fat content), compliant with EU Regulation 852/2004 and Codex Alimentarius guidelines.
How do you prepare Chestnut Flour professionally?
The primary professional technique for Chestnut Flour is Castagnaccio fry at 180°C for 30-35 min. Always verify core temperature with a calibrated probe thermometer.
Does Chestnut Flour contain allergens?
Chestnut Flour is free from all 14 EU declarable allergens under EU Regulation 1169/2011 Annex II. Always verify with your supplier for processed variants.

- 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.
