Substitutions
FAQ
Can I cook this sauce?
Heating will darken basil and reduce its fresh flavor. If preferred, simmer on low for 10-15 minutes, though the raw version best preserves the herbal notes.
What if I don't have fresh basil?
Substitute dried basil (1 tbsp), oregano, or parsley, though fresh provides the signature bright taste. Adjust quantity to preference.
How long can I keep this with the oil layer?
Up to 2 weeks refrigerated when covered with olive oil. Without the oil layer, consume within 7 days. Freezing is not recommended due to texture breakdown.
