Sablés bretons — thin Breton salted-butter biscuits
Sablés bretons are butter-forward biscuits whose name points to their sandy, crumbly texture. Semi-salted butter is the defining fat here: its salt is part of the flavour balance, so no extra salt is added. Egg yolk and caster sugar provide richness and a clean snap-tender structure, while a modest amount of baking powder keeps the biscuits from becoming dense. The dough is handled briefly and gently because excessive mixing develops gluten and works against the short texture that makes a sablé distinctive.
This preparation is deliberately thinner than a palet breton. The dough is rolled to 5 mm and the rounds bake free-standing on a lined tray. Palets bretons are typically much thicker and often need rings or moulds to contain their rise; treating the two as interchangeable would erase a useful difference between the records. After rolling, the sheet chills for 30 minutes so the butter firms and the cutters make sharp edges. Equal thickness matters more than decorative shaping because it gives all 30 biscuits the same baking time.
A fan oven at 165 °C colours the edges while the centres remain pale gold. The biscuits are fragile when first removed, so they should cool on the tray briefly and then finish cooling before being moved or packed. No butter-loss deduction is taken in the nutrition calculation: all butter in the dough is counted as eaten. Store the completely cooled biscuits dry and airtight; refrigeration is unnecessary and can soften their crisp-crumbly surface through condensation.
