Add all of the pesto ingredients to a food processor, starting with 1/4 tsp salt.Pulse until combined, scraping down the sides of the processor bowl as necessary before blending again.

Fry them over low heat, stirring occasionally, until lightly golden - this should take around 10 minutes. 40 g pine nuts, 60 g fresh basil leaves, 30 g cashew nuts, 15 g flaked almonds, 7 g nutritional yeast, 50 ml olive oil, 3 small cloves garlic, 1/4 tsp salt, 1/8 tsp ground black pepper, up to 40 ml of water to loosen the mixture
