Ingredients

• 2 cups whole milk (or any milk of your choice)
• 2 tablespoons cornstarch
• 2 tablespoons unsalted butter
• 1/2 teaspoon salt (adjust to taste)
• 1/4 teaspoon ground white pepper (or black pepper)
• 1/4 teaspoon ground nutmeg (optional, for warmth and aroma)

Equipment

• Medium saucepan
• Whisk
• Measuring cups and spoons
• Small bowl (for mixing cornstarch slurry)
• Heat-resistant spatula or wooden spoon

Instructions

1. Prepare the cornstarch slurry: In a small bowl, combine the cornstarch with about 1/4 cup of the milk. Whisk thoroughly until the cornstarch dissolves completely and no lumps remain. This step is crucial for a smooth sauce.
2. Heat the butter and milk: In a medium saucepan over medium heat, melt the butter gently. Add the remaining milk (about 1 3/4 cups) and warm it until it’s hot but not boiling — you should see steam rising and small bubbles forming around the edges.
3. Add the cornstarch slurry to the warm milk: Slowly pour the cornstarch mixture into the saucepan while whisking continuously. This prevents lumps and helps the sauce thicken evenly.
4. Cook and thicken the sauce: Continue to whisk the mixture constantly as it heats. Within 2-4 minutes, the sauce will begin to thicken. Keep stirring until it reaches a creamy, smooth consistency that coats the back of a spoon.
5. Season your sauce: Remove the saucepan from heat. Stir in the salt, white pepper, and nutmeg (if using). Taste and adjust seasoning as needed.
6. Optional – add flavor variations: At this stage, you can stir in grated cheese for a cheesy white sauce, or fresh herbs like thyme or parsley for added freshness. Mix well until fully incorporated.
7. Serve or store: Use the sauce immediately in your recipe or cover with plastic wrap (pressed directly onto the surface) to prevent a skin from forming if storing for later use.

Tips & Variations

“Whisk constantly when adding the cornstarch slurry to avoid lumps — patience here pays off with the creamiest sauce!”

Use low-fat or plant-based milks: This recipe works well with almond, soy, or oat milk for vegan or dairy-free options. Just be mindful that the flavor and texture may vary slightly.

Make it cheesy: Stir in 1/2 cup of shredded cheddar, parmesan, or your favorite cheese after the sauce has thickened for a rich, flavorful twist.

Herb-infused sauce: Add fresh or dried herbs such as rosemary, basil, or tarragon to customize your sauce for different cuisines.

Thinner or thicker sauce: For a thinner sauce, add a bit more milk; for thicker, use a little more cornstarch. Adjust gradually for best results.

Storage: Store leftover white sauce in an airtight container in the fridge for up to 3 days. Reheat gently while stirring to prevent separation.
