Story

Give the sliced onion its ten minutes alone in the lemon juice before anything else joins it. Acid blunts the sulphur compounds that make raw onion taste like an argument, and at the same time it swings the purple pigment in the skin round to a hot, improbable pink. That colour is your timer. When the slices have gone properly pink they have also gone properly mild, and you can stop watching them.

Method

Practically a no-cook dinner, and the closest thing I have to a reward for getting through August. One pot, one small pan, and everything else goes in raw.

Toss the sliced onion with the lemon juice and a pinch of salt in a large bowl and leave it while you do everything else. It has ten minutes and it needs them.
Bring a large pot of salted water to the boil. Add the pasta and cook to package directions, dropping the corn kernels in for the last 2 to 4 minutes. They want warming through, not cooking, so the kernels still pop. Drain.
Meanwhile the onions should have turned pink. Add the diced tomatoes and 1 teaspoon salt to their bowl and leave it to sit while the pasta finishes.
In a small skillet, put the olive oil, garlic and red pepper flakes in together and only then turn the heat to medium-high. Starting garlic in cold oil is deliberate, it perfumes the whole half cup on the way up instead of scorching on contact. Let it go about 1 minute, fragrant and not remotely brown, then pour it straight over the tomatoes. It will hiss and half-cook them, which is exactly what you want.
Add the drained pasta and corn and stir well to coat. Mix in the herbs. Taste and add more lemon and salt, then keep tasting, since a dish this plain has nowhere to hide.

Serve it warm, at room temperature, or cold from the fridge tomorrow, when it is arguably better. Finish with more olive oil, more herbs, a scatter of chili flakes and dollops of ricotta if you have it in.
