Pro Tips

• For a classic Italian pesto, swap Thai basil for Genovese basil, roasted cashews for toasted pine nuts, and reduce the garlic to 2 cloves.
• To keep your pesto vibrantly green, briefly blanch the basil leaves in boiling water for 15 seconds, then immediately plunge them into an ice bath before processing.
• Store leftover pesto in an airtight jar in the refrigerator. Pour a thin layer of olive oil over the top surface to prevent browning for up to one week.
• For a nut-free version, substitute the roasted cashews with an equal amount of roasted sunflower seeds or pepitas.
