- Rinse the peaches very well and cut into thin slices. Set them apart.
- Make the pie crust: mix the flours with a pinch of salt, the butter and the vegetable oil until crumbly. Beat the egg with the yolk and pour into the crumbly mixture together with the sugar. Knead until obtaining an elastic ball.
- Roll the pie crust out into a circle over a sheet of parchment paper and sprinkle some biscuits on top. Arrange the peach slices forming a circle and fold dough edges over. Sprinkle with cane sugar and bake at 180 degrees for about 30min.
- Once ready, brush the peaches with the jam and serve the galette with some ice cream or whipped cream.
