COOKING INSTRUCTIONS
Begin by preparing all your ingredients. Wash the Thai basil leaves thoroughly to remove any dirt or grit. If using whole nuts, lightly toast them in a dry skillet over medium heat for a few minutes until fragrant.
In a food processor or granite mortar and pestle, combine the dry ingredients first: the Thai basil, nuts, cheese, and chilies. Pulse or grind until the mixture is finely chopped and well combined.
Next, add the garlic, lime juice, lemon zest, and lemon juice to the mixture. Continue to blend until the ingredients are fully integrated and smooth.
While the processor is running, gradually drizzle in the olive oil or neutral oil of your choice until you achieve your desired consistency. If you prefer a thinner pesto, add more oil.
If you're using oyster sauce or fish sauce for added umami, stir it in at this stage, adjusting the amount to suit your taste preferences.
Taste the pesto and adjust the seasoning if necessary. You can add more lime juice, salt, or chilies depending on your flavor preference.
Transfer the pesto to an airtight container or mason jar. It can be stored in the fridge for up to 7 days or frozen for up to 6 months.
