### Instructions:

### 1. **Cook the Fettuccine:**
   - Bring a large pot of salted water to a boil. Add the fettuccine and cook until just **al dente** (about 1-2 minutes less than package instructions).
   - **Reserve 1 cup of pasta water** before draining the pasta.

### 2. **Prepare the Alfredo Sauce:**
   - In a large skillet or pan over **medium-low heat**, melt the **butter**.
   - If using garlic, add it to the butter and cook gently for about 1 minute until fragrant (don’t let it brown).
   - Slowly pour in the **heavy cream**, stirring continuously. Let the cream simmer gently for **2-3 minutes** to thicken slightly.

### 3. **Add the Cheeses:**
   - Lower the heat to **low** to prevent the cheese from clumping.
   - Gradually whisk in the **Parmigiano-Reggiano** and **Pecorino Romano** (if using), stirring until the sauce becomes smooth and creamy.
   - Add a pinch of freshly grated **nutmeg** for a subtle warmth and extra creaminess.
   - If the sauce is too thick, add **pasta water**, a few tablespoons at a time, until the sauce reaches your desired consistency.

### 4. **Toss the Pasta:**
   - Add the drained fettuccine to the sauce and toss gently, making sure the pasta is fully coated in the creamy Alfredo sauce.
   - Add more **pasta water** as needed to adjust the sauce’s thickness. You want the sauce to cling to the pasta but remain silky and glossy.

### 5. **Season and Serve:**
   - Taste the sauce and adjust seasoning with **salt** and freshly cracked **black pepper**.
   - Remove from heat and, if desired, add a small amount of **lemon zest** for brightness.
   - Plate the Fettuccine Alfredo and garnish with more freshly grated **Parmigiano-Reggiano**, a sprinkle of **parsley**, and a touch of **black pepper**.

### Tips for Success:
- **Pasta Water**: The starchy water is essential for thinning the sauce and helping it cling perfectly to the pasta.
- **Freshly Grated Cheese**: Always use freshly grated Parmigiano-Reggiano for the smoothest, creamiest sauce.
- **Controlled Heat**: Keep the heat on **low** when adding the cheese to prevent clumping and ensure a silky sauce.
- **Balance the Richness**: Optional additions like garlic, nutmeg, and lemon zest can balance the richness of the cream and butter.

Serve this dish immediately to enjoy the sauce at its best—smooth, rich, and perfectly coating every strand of fettuccine!
