The humble cheese grater—an unassuming kitchen staple—proves to be one of the most versatile tools in culinary prep. From shredding cheddar for tacos to zesting citrus for baked goods, this multi-sided device has earned its place in every cook’s arsenal. However, while most home chefs are familiar with the first three sides, the mysterious fourth side remains an enigma to many.
What is it for? How can you use it effectively? Let’s unlock the secret of the cheese grater’s fourth side and discover how it can elevate your cooking game.

Understanding the Four Sides of a Cheese Grater
Before we delve into the fourth side, let’s take a look at what each side of a traditional box grater is designed for:
- Side 1: Large Holes (Shredding Side)
The most commonly used side, these large openings are ideal for shredding cheese, potatoes, and vegetables like zucchini and carrots. Perfect for melting cheese on pizza or preparing hash browns. - Side 2: Medium Holes (Coarse Grating)
Slightly smaller than the shredding holes, this side is great for semi-hard cheeses, vegetables, and even grating butter for flaky pastry dough. - Side 3: Small Holes (Fine Grating or Zesting)
Used for finely grating Parmesan cheese, zesting lemons, or creating small shreds of garlic, ginger, or nutmeg. - Side 4: The Mystery Side (Ridges or Sharp Perforations)
This is where the magic happens! This lesser-known side, often featuring small, sharp, and slightly raised perforations, is designed to transform firm foods into a fine, powdery texture.
Unlocking the Power of the Fourth Side
This often-overlooked side is far more than a design afterthought. Its purpose is to finely grate and crumble firm ingredients. Here’s how you can use it to its full potential.
Step 1: Choose the Right Ingredients
The fourth side works best with solid, hard foods that can break down into tiny granules or powder. Great options include:
- Hard cheeses like Parmesan, Pecorino, or aged cheddar
- Chocolate bars for dusting desserts
- Stale bread for homemade breadcrumbs
- Nutmeg, cinnamon sticks, or whole spices for fresh seasoning
Step 2: Set Up Your Workspace
For efficient and safe grating:
- Place the cheese grater over a clean cutting board or plate.
- Hold the grater firmly with one hand for stability. If it slips, set it on a damp cloth to keep it steady.
Step 3: Grate with Control
- Hold your chosen ingredient securely and press it gently against the fourth side.
- Use light, controlled strokes to move the ingredient downward, letting the sharp perforations do the work.
- Rotate the ingredient occasionally for even grating.
Step 4: Collect Your Grated Goodness
- As you grate, a fine, powdery texture will gather on the plate or board.
- Scrape the inside of the grater to collect any remaining particles—they are often the most flavorful.
Step 5: Use Your Freshly Grated Ingredients
The fine texture from the fourth side is perfect for:
- Sprinkling chocolate or cinnamon over cakes, cookies, or coffee.
- Adding a delicate layer of Parmesan to soups, pasta, or salads.
- Making ultra-fine homemade breadcrumbs for coating meats or thickening soups.
- Enhancing recipes with freshly grated nutmeg or cinnamon for bold, aromatic flavors.
Step 6: Clean with Care
This side’s tiny holes can trap food particles, making cleaning tricky. Follow these steps:
- Rinse immediately under warm running water.
- Use a soft brush or toothbrush to scrub out any residue.
- Dry thoroughly before storing to prevent rust.
The Fourth Side: No Longer a Mystery
Once an overlooked feature, the fourth side of the cheese grater is now revealed as a powerful tool for enhancing your cooking. Whether you’re dusting cocoa over a tiramisu or topping pasta with a whisper of freshly grated Parmesan, this underappreciated side adds finesse and precision to your dishes.
Next time you reach for your cheese grater, remember: every side has a purpose, and the fourth side just might become your new favorite kitchen trick.
