Chestnut Flour
Chestnut Flour (also: Farine de châtaigne | Castagnaccio flour). Naturally sweet, earthy, dense. Characteristic autumn flavour.
Naturally gluten-free. That describes the plant. On a pack, any gluten-free wording, 'naturally gluten-free' included, legally means the flour inside is within the 20 ppm limit (EU, UK, US); flour without it can pick up gluten in the mill. IT cultural relevance: central to Tuscan cuisine. Chestnut allergy distinct from almond/hazelnut.
