Frequently Asked Questions

Can strict vegetarians eat regular restaurant pesto?
Usually no. Authentic Italian Parmigiano-Reggiano and Grana Padano legally require animal rennet under EU PDO regulations, making standard pesto non-vegetarian and non-vegan.
How to make a quick 5-minute vegan pesto?
Pulse fresh basil, toasted pine nuts or walnuts, minced garlic, extra virgin olive oil, nutritional yeast flakes, lemon juice, and sea salt in a food processor.
