Nuts: Toast the almond and pecan nuts in a pan on medium low heat. Add it to a blender and pulse until it is in powder form.
Garlic: Add the grapeseed oil to a small pan on medium low heat. Add the sliced garlic and then add the red chili flakes once the garlic has turned a golden brown.
Make the pesto: Wash and clean your basil leaves. Add your Thai basil leaves to the blender and pulse a few times until the leaves have reduced in size, then add the garlic and ground nuts with the red chili flake oil to the blender. Pulse a few times.
Toast the Pesto: This part helps the spices to meld with one another. Add the pesto to the same small pan used for the garlic. Add a knob of butter, add oyster sauce, brown sugar, salt and rice vinegar and toast up the pesto until the colour turns a deep green. Add the parmesan cheese and mix. Thereafter, taste and serve with your favourite pasta.
