Orange slices are a light almond sponge sheet with a chestnut filling and a fragrant orange coating. Chestnut and orange are an old, well-known pairing, because the freshness of orange offsets the heaviness of chestnut. With ready-made chestnut purée the filling is done in minutes.
Preheat the oven to 170°C and line a tray of about 25×35 cm with baking paper.
Beat the egg yolks with the sugar and grated orange zest with a mixer until fluffy, then add the almonds and breadcrumbs.
Whisk the egg whites with the pinch of salt until stiff and fold them gently into the mixture in two batches.
Smooth the batter into the tray (about 2 fingers thick) and bake at 170°C for 25-30 minutes, until golden brown and a toothpick comes out dry. Cool on a rack.
Mix the chestnut purée with the icing sugar and orange juice until smooth. Cut the cooled sheet in half, spread one half with the chestnut filling, place the other half on top and press lightly.
Coat the top with orange glaze, leave it to set, then cut into slices with a sharp knife.

Tips
Use the zest of an organic, unwaxed orange, grated.
Fold the egg whites in gently, which keeps the sponge light.
Let the sheet cool completely before cutting it in half and filling it.
For an orange chocolate glaze, melt chocolate with a little orange juice and butter.
It keeps in the fridge, covered, for 4 days.
