Avoiding clumps in cacio e pepe?
I've been trying to make a very basic three-ingredient cacio e pepe over the last few days and have found it difficult to create a smooth, creamy sauce.
I'm using only two cups of microplane-grated pecorino romano cheese, a handful of spaghetti, and crushed black pepper. Salt in the pasta water, too, of course.
I've tried it two ways and gotten varying results:
- Cooking the pasta shallow water in a wide pan to concentrate the starch. Then, drain, lower the heat and add the pasta back in with a few ladles of water and adding the cheese gradually, tossing stirring violently with a wooden spoon.
- Add some of the pasta water to the cheese in a separate bowl a few minutes before the pasta finishes cooking. Whisk the pasta water and cheese into a paste, then add the finished pasta to it with some extra water and, again, stir like crazy.
Neither seems to work very well, though my best results so far came from (1), but I'm quite convinced it was luck. What might I be doing wrong or overcomplicating? Everything I see on the Internet says it should be "very easy", but the lack of videos showing this recipe has made it difficult to learn. The videos I have seen use a lot of olive oil and butter, which I'm told is absolutely not traditional or okay.

Achieving a creamy sauce for cacio e pepe, and dishes like it (carbonara comes to mind) is not as straight forward as some would have you think. Fortunately, while we strive for the perfect emulsification, those attempts that don't exactly work are still delicious.
Here are some tips:
(1) Make sure your cheese is grated as finely as possible, and that it is at room temperature or warmer. A microplane is perfect.
(2) The water you add can't be too hot. Scoop some pasta water out halfway through the cooking process, allow it to cool, and use that to add later.
(3) Drain pasta and allow to cool a minute before dressing.
(4) Some find that combining pasta and cheese in a cool pan is better (so that you can control heating).
(5) Some combine the water and the cheese, then add that mixture to the pasta.
(6) The addition of fat (butter, cream, oil) helps the cheese to emulsify, but this addition varies and is sometimes not included.
It's all about practice and adjustment. Much of this information came from here, and I can vouch for more success (sadly,not perfection) using these techniques.

Why is my cacio e pepe stringy?
On the flip side, if you heat the cheese too harshly, the proteins will coagulate, and you will be left with stringy, unappealing clumps of cheese, and again\u2026 a broken sauce - this is where most attempts at cacio e pepe fail. As you might imagine, the trick to getting the cheese right is getting the temperature right.How do you keep cheese from clumping in pasta?
Hot liquids, like pasta water, heavy cream, melted butter, or beaten eggs, help distribute melted cheese evenly by surrounding it with heat. Since every bit of surface area is in contact with hot liquid, the cheese melts at the same rate. No clumps to be found, just a glossy, luscious sauce.Why is my Alfredo clumping?
Dairy or egg-y sauces can curdle for several reasons: There might not be enough fat in the sauce; skim milk will curdle much more easily than other, fattier dairy products. High heat can also cause sauces to curdle; low and slow is the safest option.Can I use Parmesan instead of Pecorino in cacio e pepe?

Answer 2
If you don't care about being at all traditional, you can take out a cup of the pasta water just before al dente and measure out 2% of the weight of the water plus the cheese in sodium citrate. Whisk it in to the water, then add the cheese bit by bit. It's then safe to add the pasta and cook the rest of the way, adjusting with more cheese or pasta water as needed.
Sodium citrate is detailed more in Modernist Cuisine, but the key detail is that it keeps even hard cheeses emulsified. The sauce simply will not clump this way. It has a salty, slightly citrusy taste, but it's easily overpowered by pecorino or parm.
If you're sensitive to sodium or don't keep that ingredient around (what? doesn't everyone have a molecular gastronomy hobby?) then you can get similar results with an immersion blender. Again reserve some starchy pasta water into a narrow blender cup and add the cheese slowly while running the blender. Keep plenty of cheese around to adjust the consistency. Then it's safe to toss in a warm bowl with the pasta.
