Making an Incredibly Simple Nacho Cheddar Sauce!

Nacho Cheddar Sauce.. My mouth is salivating as I think about it. There’s only one problem. Melting fresh cheddar cheese isn’t as easy as it sounds. It tends to split and get grainy when too much heat is applied, when too much is added at once, and so on… Who knew there were so many rules to melting cheese!!

The reason this happens is because cheese is a delicate emulsion of fat and water held together by proteins and as you heat your cheese up the proteins begin to denature. The more moisture you have the better your cheese will melt (generally speaking) and the ooey gooey melted chhese that’s on pizzas or hamburgers is a result of the protein breaking down causing the structure to begin to sag. Cheese with lower moisture levels, like aged cheese will have a much harder time doing this as the bond is much weaker. This means that the possibility of that emulsion breaking is more likely.

What if I told you that you could add a very specific type of salt to your cheese to stop this from happening. This salt acts as an emulsifier and keeps the particles bound properly regardless of the moisture content.

This isn’t any ordinary salt as it’s not going to make your cheese sauce salty. It’s a salt from citric acid called sodium citrate and can easily be made by combining baking soda and citric acid in some water then cooking it down. There are a few websites that show you how to do it but for me I just go to Amazon and get a few pounds.

This stuff is amazing. Talk about a nacho cheese game changer. Forget about nachos for a minute and think about all of the possibilities. This salt can literally turn any cheese into the most luxurious, velvety, creamy, cheese ever! Bleu cheese, Gouda, feta, Munster, Swiss, you name it. Every cheese I’ve used it on it’s worked like a charm. You can even tweak the amount of sodium citrate you add to affect the density of the cheese so you can even make your very own cheese block if you want to. In a later post I’ll show you how I turned regular cheddar cheese into an amazing block of Black Garlic Guinness Cheddar Cheese. All with the help of Sodium Citrate.

It is super easy to use and once you start playing with it you’ll get the hang of it. The bottom line is this. The more liquid you add the runnier your cheese will be. The less liquid you add the more dense your sauce will be.

I’ve been incorporating this cool ingredient into my broccoli cheddar soups, mac and cheese (WHAT!!!!), all sorts of recipe that call for cheddar to be added. You will never have a grainy cheese no matter how hot you heat it. I’ve been using this for years and still to this day when I melt my fresh cheeses I am amazed at how it works. Science, Mr. White!!

    What’s the ratio of cheese to liquid to sodium citrate? Say for example I have a regular 2 cup bag of shredded cheese.

    1. Eric

      It varies depends on the consistency that you want your sauce. But a good place to start is 1 pound of cheese to 1 cup of liquid, to 1 tsp of sodium citrate. If you add more liquid the cheese sauce will be thinner.

  2. Jacob

    What happens when this gets cold? Does it stay in the sauce form or does this become a semi-solid block?

    1. Eric

      It firms back up (semisolid)

      1. Jacob

        And what if I wanted it to stay thick and liquid, like mustard. Do I just add more of the sodium citrate?

        1. Eric

          Add more liquid. It thickens as it cools. It’s a funny balance of experimenting.

  3. Adele

    How would you make a cheese sauce for macaroni and cheese using sodium citrate?

    How long will this keep in the fridge? Can it be frozen?

    1. Eric

      You can keep this in the fridge for 4-5 days. It can be frozen..

  5. Kito

    Does the sodium citrate make it shelf stable?

    I made as directed using chicken broth for the liquid. It NEVER really thickened. I added another 1/4 tsp. but still was very soupy!

    1. Eric

      This cheese sauce has never failed me. I’ve used it with beer, milk, water, stock, you name it. Here is the recipe again. 1 cup of liquid, 1 tsp of sodium citrate, and 1 pound of fresh cheese (not pre grated cheese). If your cheese has a coating of corn starch or some other additive it might not work. Dissolve the sodium citrate in the liquid and bring to a simmer. Slowly add the freshly grated cheese to the liquid and continuie to cook on a medium heat. Stirring often you will watch that cheese literally melt before your eyes and turn into an awesome sauce. What type of cheese did you use?
