Preparation
- Step 1
Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente. Reserve 1 cup pasta cooking water, then drain the pasta.
- Step 2
Meanwhile, using the large holes of a box grater, grate the cut ends of the tomato into a large bowl. Discard or compost skins. Grate the butter into the bowl as well. Using the small holes of the box grater, grate the garlic into the bowl. Add the red-pepper flakes, and season generously with salt. Refrigerate until ready to use.
- Step 3
Return the drained pasta to the pot, along with the bowl of grated tomato and butter. Set over medium-high heat and cook, stirring constantly, until the mixture thickens slightly and glosses the pasta, 2 to 3 minutes (the sauce will thicken as it sits). Add pasta water as needed to emulsify the sauce. Season to taste with salt and pepper. Serve with more red-pepper flakes, black pepper, basil and Parmesan as desired.

In Italy we make versions of this pretty much every day in summer, with either olive oil (south) or butter (north), minus the raw garlic which Italians find indigestible. Easier to start heating the sauce in a pan, then transfer the under-cooked pasta with a slotted spoon, incorporating some water--no colander needed. Here leftover pasta is never saved much less eaten cold; it goes right to the dog.
It seems the author (and many readers) are conflating "al dente" with "under-cooked." Here in Italy, al dente is ready to eat. If you cook the pasta al dente and then cook it 2-3 minutes longer, it will be mush. The recipe should have said to cook the pasta 2-3 minutes less than al dente.
To avoid over-cooking the pasta: instead of cooking it al dente and then adding it back to the pot, cook the pasta until it’s done, reserving some of the cooking water. Drain the pasta and immediately transfer it to a big bowl. Add the sauce, the Parmesan cheese, and a little of the reserved pasta water. Stir vigorously, using a whisking motion. Add more cheese and more water if needed, and stir again. The sauce forms beautifully in less than 30 seconds and the pasta will be perfect.
Heat sauce in pan and then add noodles by the spoonful without draining. Use 3 garlic cloves
Everyone saying to undercook the pasta by a couple minutes is lying, though maybe it depends what type of pasta you're using. Cook according to box instructions, freeze butter before grating. Made using farmer's market heirloom tomatoes and Kerrygold butter, comes together fast and tastes just as good the next day. Add more basil than you think you need, too. You don't *need* it, but it tastes great.
The tomato tasted good but I added parm at the end and it all seized up rather than emusifying?
