Start with less
A tomato sauce does not need a crowded ingredient list. Start with olive oil, a little garlic, and tomatoes you enjoy eating. Warm the oil gently, then add the garlic. The goal is fragrance, without the sharp bitterness that comes from burning it. Add the tomatoes and let the pan settle into a gentle simmer.
Taste before reaching for more ingredients. Tomatoes vary in sweetness, acidity, and water content, so a fixed cooking time can only tell you so much. Look for a sauce that tastes rounded and clings lightly to a spoon.
Let the pasta finish the dish
Before draining the pasta, save a mug of its cooking water. Move the pasta into the sauce while it still has a little bite. Add a splash of the reserved water and toss over gentle heat. The water helps the sauce spread evenly instead of sitting in a puddle at the bottom of the bowl.
Add the liquid gradually. You can always add another spoonful, but an overly loose sauce takes more time to bring back together. Stop when the pasta looks glossy and each ribbon carries a little sauce.
A small finishing ritual
Tear basil by hand and add it near the end. Finish with a drizzle of olive oil and, if you like, finely grated hard cheese. Serve in warm bowls, bring the rest to the table, and leave room for everyone to make the last adjustment themselves.
Try this next time: change only one ingredient. Compare two kinds of tomatoes or two olive oils. Paying attention to one change is a simple way to discover what you love.
