Nut Slices with Egg Yolk Glaze

Preheat the oven to 160 °C. Line a baking sheet with parchment paper.

Cream butter with sugar until foamy. Stir in flour and finely grated nuts. Whisk egg whites into stiff peaks and carefully fold them into the batter in portions.

Spread the batter onto the baking sheet lined with parchment paper, use a pastry scraper to spread it to the edges of the sheet and smooth the surface. Place the baking sheet into the preheated oven and bake for 30–35 minutes.
