Sablés bretons come from Brittany — the northwestern French peninsula with a Celtic heritage and a dairy tradition built on some of the world's finest butter. The defining ingredient is Breton salted butter: butter made from the cream of cows grazing salt-marsh pastures, with large fleur de sel crystals incorporated. The contrast of rich butter and the crunch of salt crystals on the palate is what makes sablés bretons distinct from every other shortbread tradition.
Breton Salted Butter
Brittany was historically exempt from France's salt tax (the gabelle), which meant Breton cooks salted their butter generously when cooks elsewhere in France used unsalted butter out of economic necessity. The salted butter tradition became so embedded in Breton cooking that it defines the region's pastry and biscuit character. Use a good quality salted butter for this recipe — Kerrygold salted, or specifically a French brand if available.

Can I use unsalted butter and add salt?
Use unsalted butter and add 1/2 tsp fleur de sel to the dough, plus a pinch on top of each biscuit before baking. The fleur de sel on top is important for texture.
Why rest the dough?
Resting allows the butter to firm up so the biscuits hold their shape during baking. Warm dough spreads too much in the oven.
How do I know when they're done?
The bottoms should be golden and the tops pale golden. They should feel firm at the edges and slightly soft in the centre. They firm completely as they cool.
