Gâche normande: milk-enriched Cotentin brioche loaf
Gâche normande in this version is a Cotentin-style milk-enriched loaf. Wheat flour, whole milk, butter, egg and baker’s yeast produce a soft brioched crumb, but the formula is kept distinct from cream-based gâche vendéenne and from the dried-fruit gâche associated with Guernsey. The loaf form, milk basis and single rise define the household method used here.
Because the dough is rich, butter must disappear into the gluten network rather than sit in greasy streaks. The dough is first brought together with milk and egg, then kneaded until smooth and satiny. It is shaped, scored and egg-washed before the one rise, so the proofed loaf can move to the oven without being knocked back and reshaped.
The bake is deliberately substantial: about 45 minutes at 180 °C for a large loaf. Colour alone is not enough. The bottom should sound hollow and the centre should have no wet dough line. A full hour on a rack follows, because cutting a warm enriched loaf compresses the crumb and can create the false impression that the centre is underbaked.
