Ricotta And Arugula Roulade

• 4 tbsp butter, plus more for the baking sheet
• 1/3 cup all-purpose flour
• 1 1/4 cups whole milk
• 3/4 cup freshly grated Parmesan cheese
• 2 tsp Dijon mustard
• Salt and black pepper
• 4 large eggs, separated
• 1 cup ricotta cheese
• 1 c packed cup coarsely chopped arugula

1. The roulade can be prepared through step 4 a few hours in advance of baking. The baked roulade can be refrigerated for up to 24 hours.
2. Preheat the oven to 375u0b0F (190u0b0C). Butter a 9 x 13in (23 x 33cm) baking sheet and line with parchment paper.
3. Melt the butter in a large saucepan over medium-low heat. Whisk in the flour and let bubble for 1 minute. Gradually whisk in the milk and cook, whisking often, until the sauce comes to a boil. Remove from the heat again and stir in half of the Parmesan. Add the mustard and season with salt and pepper. Allow to cool slightly, then beat in the egg yolks.
4. Beat the egg whites in a bowl until they form soft peaks. Stir one-fourth of the whites into the cheese mixture to lighten it, then fold in the remaining whites. Spread evenly into the prepared pan.
5. Bake for about 20 minutes, or until golden and the top springs back when pressed. Turn out on to a large piece of wax paper dusted with the remaining Parmesan.
6. Peel away the parchment paper and trim off the crispy edges from the roulade. Spread the surface with the ricotta, leaving a 1in (2.5cm) border at the short sides. Cover the ricotta with the arugula. Roll up the roulade lengthwise, using the paper as an aide. Cut into slices, and serve.
