Ingredients:
- 1/2 cup (115g) unsalted butter
- 1 cup (240ml) heavy cream
- 1 1/2 cups (150g) freshly grated Parmesan cheese
- 3 cloves (15g) garlic, minced
- 1/4 tsp (1.5g) ground nutmeg
- 1/2 tsp (3g) kosher salt
- 1/4 tsp (1g) cracked black pepper
Instructions:
- Melt the butter over medium low heat. Once foaming, add the minced garlic and sauté for about 60 seconds until fragrant but not brown. Note: Browned garlic becomes bitter.
- Pour in the heavy cream and stir in the ground nutmeg.
- Increase the heat slightly to bring the mixture to a gentle simmer for 3–5 minutes until it reduces slightly and thickens.
- Turn the heat to the lowest setting or remove the pan from the heat entirely. Note: This is the most critical step to prevent the cheese from separating.
- Gradually whisk in the freshly grated Parmesan cheese, one handful at a time.
- Whisk vigorously until the sauce is glossy and uniform.
- Stir in the kosher salt and cracked black pepper.
- If the sauce is too thick, whisk in a tablespoon of reserved pasta water until the consistency is velvety.
