2Add a little water to the bottom of the pan to help get it started.
3Place the pot on the stove over low heat and cover.
4Add a little bit of salt to the tomatoes to help release moisture.
5Once moisture accumulates, increase the heat to bring to a boil.
6Add the basil stems and basil leaves to the pot.
7Cook the tomatoes for about an hour, or until they are super soft and mostly skins and seeds remain.
8Strain the cooked tomatoes using a fine mesh strainer placed over a bowl to collect the tomato water.
9Season boiling water with enough salt to taste like a seasoned broth.
10Drop the spaghetti into the boiling water and cook for about 7 minutes.
11Meanwhile, in a pan or saucier, turn the heat on low and add about a cup of tomato water per person.
12Dice the cold butter.
13Remove the pasta from the boiling water and add it to the tomato water in the pan.
14Turn up the heat and cook the pasta in the tomato water for another 5 minutes, swirling it around to release starch and reduce the tomato water to a glaze.
15Check the pasta for al dente; if still undercooked and the tomato water has reduced, add a little more tomato water at a time until al dente and the spaghetti is glazed.
16Turn off the heat and add in the cold diced butter, swirling and tossing until it completely melts and emulsifies into the sauce, clinging tightly to the spaghetti.
17Plate the pasta by picking it up with pasta tongs, cradling it in a ladle, swirling it into a bundle, and transferring it to a plate.
18Top with a little bit more sauce (if running low, add a touch more pasta water to the pan for yield).
19Finish with a little bit of fresh basil and grated Parmesan.

Tips
To cut cherry tomatoes quickly, place them between two lids and slice through the middle horizontally.
Puncture cherry tomatoes before boiling to help them release juice.
For more servings, use about a cup of tomato water per person.
Finish the pasta in the tomato water to allow the pasta starch to be released and glaze the spaghetti.
If the tomato water reduces too much before the pasta is al dente, add a touch more pasta water.
Swirl cold butter into the pasta off the heat to emulsify it into the sauce.
To plate, use pasta tongs and a ladle to create a neat bundle of spaghetti.
You can use the leftover tomato skins and seeds to make another sauce or tomato jam.
