What are common mistakes when making Castagnettes — Chestnut-Flour Shortbread Rounds?

1. Warm butter — greasy dough that won't bind. 2. Omitting the wheat flour entirely — rounds crumble and fall apart. 3. Rolling the dough — tough result. 4. Lifting from the tray before fully cool — they break.

Castagnettes — Chestnut-Flour Shortbread Rounds

I · Origin

Corsica, France — gift and café tradition island-wide; Castagniccia specialty shops

II · Description

Small, dense rounds of chestnut-flour shortbread — 3cm diameter, 1cm thick — made from Farine de Châtaigne Corse IGP, Bos taurus unsalted-butter, caster-sugar, and a small proportion of Triticum aestivum plain-flour (10%) to provide the structural gluten that pure chestnut-flour shortbread lacks. The butter is cut into the flour until the mixture resembles breadcrumbs, then formed by pressing — not rolling. Baked at 160°C for 18 minutes. The result is a crumbly, sandy-textured round with concentrated chestnut-sweetness and butter. Served with coffee or espresso in coastal cafés. Also a common gift item: sold in boxes in Corsican specialty shops. Distinguished from Canistrelli by the absence of anise and the pressed (not rolled-and-cut) production method.
