Will It Sous Vide? Melty Cheese Sauce From Any Cheese

Hello, everyone, and welcome back to a particularly gooey episode of Will It Sous Vide?, the column where I conduct food experiments with my immersion circulator.

Gooey, cheesy sauces is what we’ll be playing with today, and I was not at all mad about it. I had been wanting to play around with melting salts for a while, so I placed a hasty online order for food grade sodium citrate and gathered up a bounty of various cheeses.

Before we get to gooey stuff though, let’s talk about those melting salts, particularly sodium citrate. If you’ve ever melted a hard cheese like cheddar, you probably noticed that it tends to separate into a gloppy, greasy mess. Sodium citrate prevents this by acting as an emulsifier, reducing the cheese’s acidity (increasing the pH) and making the proteins more soluble. This, plus the addition of a little water, lets a solid piece of cheese melt down into a creamy sauce that won’t separate or break.

I had heard that this would work for any cheese, but I had a hard time believing it was a one-size-fits-all kind of situation. Different cheeses have different levels of acidity, and it seemed unlikely that a cheese like asiago or parm would behave like cheddar.

I decided to start with cheddar as a baseline — it’s hard, but not like, “parm hard” — and, using this article as a starting point, filled a quart-sized freezer bag with the following:

  • 113.3g of sharp cheddar cheese, sliced thin
  • 1/4 teaspoon of sodium citrate
  • 1/4 cup of water (You can also use beer, sherry, or wine.)

I then submerged the bag in a water bath set to 75°C and waited for the cheese to melt. After about five minutes, the cheddar seemed to be sufficiently liquefied, so I dumped the contents of the bag out and blended it up with an immersion blender to get everything emulsified.


No good.


Heyo!

I prepared each cheese as I had the cheddar, and chucked the resulting bags in the bath for 15 minutes. After a quarter hour in the tub, I pulled everyone out and hit ’em with the immersion blender. The results were varied, to say the least

Would you look at that?

Asiago

This one gave me the most trouble. As you can see from the above photo, 1/4 teaspoon of sodium citrate simply wasn’t enough to get Asiago to play nice. It was clumpy and stringy, and started to solidify almost immediately.

Unlike the cheddar and Havarti, this issue didn’t seem like it would be fixed with more time, so I added another 1/4 teaspoon of melting salts and chucked it back in the water bath. After another fifteen minutes, the texture was only slightly improved, so I added yet another 1/4 teaspoon of sodium citrate plus a tablespoon of water.

That did the trick. Though this was definitely the thickest of all the sauces, it was at least a sauce now, ready to have all sorts of things dipped into it. Actually, though this would make a decent dip, I think it belongs on a burger. Asiago prepared this way has the texture and mouthfeel of the meltiest American cheese, without tasting like American cheese. It truly is a thing of beauty.

Parmesan

Parmesan behaved exactly like Asiago, but I dropped it on the floor before I could get any pictures of it, so you’ll just have to take my word for it.

Mix It Up

I prepared this little collection as I had that initial bag of cheddar, only this time I used sherry instead of water. (This turned out to be a very good decision.) After fifteen minutes in the tub, I blended it all up and poured it into a bowl.


Perfection (That’s a purple baby carrot, not some sorta creepy finger.)

And now we must ask ourselves our favourite question: Will cheese sauce sous vide?

The answer: Oh hell yes, though there isn’t one recipe that works perfectly for every type of cheese. There is, however, a general procedure that will let you transform any cheese — hard or soft — into a dreamy, creamy, gooey sauce:

  1. Start by weighing out four ounces of cheese, and add a 1/4 cup of your liquid of choice, along with a quarter teaspoon of sodium citrate. (You can of course scale this up, just make sure you increase your liquid and melting salt along with the cheese.
  2. Put it all in a bag, and place it in a bath set to 167℉. After fifteen minutes, hit it with a blender of some sort and see how it behaves. If it emulsifies into a silky sauce, you’re all done! Stop here and enjoy your cheesy creation. But if your cheese isn’t playing nice, proceed to step 3.
  3. If your sauce has small, lumpy clumps (like our cheddar and Havarti initially did), simply transfer it back to its bag and let it hang out in the bath a little longer. If however, your cheese is forming into one large mass, clumping together and clogging the blades of your blender, you need a little more sodium citrate. Add another 1/4 teaspoon, return to the bath for another fifteen minutes, and try blending it again. Repeat until you reach your desired consistency.

Once you have your sauce all sussed out, your ready to get to dipping. I recommend enjoying it fairly quickly as it will eventually turn into a Velveeta-like mass, but it reheats easily enough over a water bath with some gentle whisking.
