1 8.8-ounce package dried egg fettuccine (such as De Cecco)
4 1/2 tablespoons butter
20 fresh sage leaves, stemmed
4 1/2 tablespoons frozen veal stock, thawed, or 2 tablespoons beef broth and 2 1/2 tablespoons low-salt chicken broth
5 tablespoons grated Parmesan cheese plus additional for serving PreparationCook pasta in large pot of boiling salted water until tender, stirring occasionally. Drain, reserving 1/2 cup cooking liquid.
Meanwhile, melt butter in heavy large skillet over medium-low heat. Add sage leaves and cook until edges curl and butter is dark amber (do not burn), stirring and turning leaves occasionally, about 6 minutes. Transfer sage to paper towels. Add veal stock to brown butter.
Add pasta and 5 tablespoons grated Parmesan cheese to brown butter mixture in skillet; toss to coat, adding reserved cooking liquid by tablespoonfuls if dry. Season with salt and pepper. Divide among bowls. Garnish with fried sage leaves, passing cheese alongside.
TEST-KITCHEN TIP: In this recipe, the brown butter isn’t strained, but it is in the shortbread and the ice cream. Why? In some recipes, the milk solids are strained out of the brown butter to ensure a smooth texture. In others, the brown butter is strained because it will be cooked with other ingredients and the milk solids might burn.
