- Why is the sauce grainy?
- You likely cooked the cheese at too high a temperature, or used low-fat cheese. The proteins clumped together.
- Can I use pre-shredded cheese?
- Not recommended. Pre-shredded cheese is coated in starch to prevent sticking, which prevents the sauce from becoming perfectly smooth.
- It's too thick, what should I do?
- Stir in a little more warm milk until you reach the desired consistency.
Jalapeño Cheddar Cheese Sauce
This isn't just melted cheese; it's a classic Mornay sauce made famous by Tex-Mex cuisine. The secret lies in the roux (butter and flour base), which stabilizes the milk so the cheese doesn't separate but forms a creamy, velvety emulsion. The acidity and heat of the jalapeño cut through the richness of the cheese, keeping every bite fresh.

Instructions
1
✓
Prep ingredients: shred the cheese and garlic, and finely dice the jalapeños.
Tip: Shred cheese while cold, but let it come to room temperature before melting for smoother results.
2
✓
Melt butter in a saucepan over medium heat. Whisk in flour and cook for 1-2 minutes until pale golden.
Tip: This is a roux. You must cook the flour taste out, or the sauce will taste pasty.
3
✓
Gradually whisk in the milk in small splashes, whisking vigorously.
Tip: Adding milk slowly is the key to a smooth texture.
4
✓
Simmer on low until thickened (3-4 minutes), then remove from heat.
Tip: Reduce heat or remove entirely before adding cheese to prevent separation.
5
✓
Stir in the shredded cheese a handful at a time until melted and smooth. Stir in the garlic and jalapeños.
Tip: Sharp cheddar gives a stronger flavor.
6
✓
Season with salt and pepper. Taste and adjust.
Tip: Be careful with salt, as cheese is naturally salty.
