Buckwheat Galettes with Leeks and Mushrooms
The lacy, nutty galette of Haute Bretagne, filled with leeks melted slowly in salted butter, browned mushrooms and a handful of grated cheese. The batter asks for nothing but buckwheat, water and salt, plus patience overnight.
Ingredients
- 250 g buckwheat flour
- 550 ml cold water
- 1 egg
- 1 tsp coarse grey sea salt
- 90 g salted butter, divided
- 2 large leeks, white and pale green, sliced
- 250 g button or cremini mushrooms, sliced
- 120 g grated Emmental or Gruyère
- 2 tbsp crème fraîche
- Freshly ground black pepper
Method
- Whisk the buckwheat flour, water, egg and salt into a smooth, thin batter. Cover and rest it in the refrigerator overnight, or for at least 3 hours.
- Melt 30 g of the butter in a wide pan over low heat. Add the leeks with a pinch of salt and cook gently for 15 minutes until silky, then stir in the crème fraîche.
- In a second pan, brown the mushrooms in 20 g of butter over high heat until their water has cooked away. Season and set aside with the leeks.
- Heat a large flat pan or crepe pan until properly hot. Grease it with a little of the remaining butter, ladle in a thin layer of batter and swirl to coat.
- When the edges lift and the underside is deeply browned, scatter a quarter of the cheese, leeks and mushrooms over the center.
- Fold the four sides in to make an open square, slide onto a warm plate, and finish with a knob of salted butter. Repeat for the remaining galettes.
