This dish is classically Ligurian, combining trenette pasta with pesto, which originated in Genoa, Liguria’s capital. While trenette (which is rectangular in shape instead of flat like linguine) is available from some Italian food shops and selected delis here, it can be difficult to track down, so we have substituted linguine for ease. Refrigerate any leftover pesto in an airtight container in the fridge for up to 1 week.
