The freshness of pesto is delicate, so preserving its vibrant flavor demands careful attention. Refrigeration, while effective, should be limited to a few days, as freezing can compromise the texture and subtle nuances. To extend its shelf life while maintaining its culinary integrity, opt for these practical methods:
