This practical tip is classic Guarnaschelli: Approachable, effective, and perfect for the everyday cook. But what if you could avoid clumps altogether in the first place?

Start by choosing your cheese wisely — grating cheese instead of using pre-shredded varieties makes a big difference. Pre-shredded cheese often contains anti-caking agents like potato starch or cellulose, which help prevent clumping in the bag but can interfere with the melting process.

When it comes to melting, not all cheeses are created equal. Some cheeses naturally have a better texture for sauces. For a sauce that stays velvety, cheeses like Gruyère, Fontina, or Monterey Jack are your best friends. Their creamy, high-moisture content allows them to melt effortlessly. On the other hand, harder or aged cheeses like Parmesan or goat cheese can be trickier — they tend to lump or separate unless melted gently or combined with a stabilizer like cornstarch or sodium citrate, both of which help emulsify the cheese and liquid for a smoother, more consistent sauce.

Temperature control matters, too. Always melt your cheese on low heat and combine it gradually with your liquid base. Adding cheese all at once or to a sauce that's too hot can cause it to seize up. With these prevention tips and Alex Guarnaschelli's quick-fix hack in your culinary toolkit, you'll never have to settle for anything less than perfect cheese sauce again.
