Toast the nuts in a pan over medium-high heat, stirring occasionally. Watch that they don’t burn.
Place the nuts, chillies, garlic, ginger, fish sauce and lime juice in a food processor. Add a handful of basil and laksa leaves, drizzle with some oil and blend.
Continue adding herbs and oil, and blend until smooth. The laksa leaves are fibrous and may clog up the blades, so use a spatula to stir the pesto in-between processing it.
Season to taste with sugar and salt. You may opt to stir in some sambal or sriracha for added heat.
Store covered with a layer of vegetable oil. Keeps refrigerated for up to 2 weeks.
