Heat oil in a small saucepan and fry garlic cloves for 2-3 minutes until golden in colour and then remove from heat.
Into a blender, place all ingredients EXCEPT DILL, and be sure not to put the hot garlic cloves in first. I always put water and cashews in first. And yes you can add the garlic + the oil it cooked in. Blend until very very smooth!
Finally whisk the dill in. Store in a glass jar in fridge for up to 4-5 days! It should thicken overnight in the fridge.
