I start by rinsing the cherry tomatoes and slicing each one in half with a sharp knife. Working in batches keeps them from rolling everywhere on the cutting board. I toss the halved tomatoes straight into a large mixing bowl as I go.
Next, I peel and mince six cloves of garlic as finely as I can manage. The smaller the pieces, the more evenly the flavor spreads through the oil during marinating. I add the garlic directly into the bowl with the tomatoes.
I julienne the basil leaves right before adding them, since basil discolors quickly once it's cut. Into the bowl it goes, along with the olive oil, red pepper flakes, a good teaspoon of kosher salt, and the black pepper.
I stir everything together gently so the tomatoes don't get crushed, then cover the bowl and let it sit at room temperature for about four hours. During this time, the tomatoes release their juices and mingle with the garlic and oil to build real flavor.
When I'm about ready to serve, I bring a large pot of salted water to a boil, add a splash of olive oil, and cook the angel hair according to the package directions. Thin pasta cooks fast, so I stay close by and check it a minute or two early.
I drain the pasta well, since extra water dilutes the marinated tomato mixture, then add it straight into the bowl with the tomatoes. I toss in the grated Parmesan and a few more fresh basil leaves and mix everything until the pasta is coated.
This dish tastes best served warm right after tossing, while the pasta is still hot enough to slightly wilt the basil. I always keep extra Parmesan on the table for anyone who wants more.
