Ingredients:
3 tablespoons unsalted butter
2 tablespoons olive oil
2 cups heavy cream
2 cloves garlic, minced
¼ teaspoon white pepper
½ cup freshly grated Parmesan cheese

Heat butter and olive oil in a saucepan over medium-low heat until butter is melted. Mix in cream, garlic, and white pepper and bring to a simmer, stirring often, 3 to 5 minutes.
