Soak the raw/dried chickpeas in a bowl with the spring water overnight.
Put the chickpeas and left over spring water into a frying pan and cook on low heat for 1 hour with a lid. Stir every 15 minutes just to make sure they are not burning, top up with water if the chickpeas are not fully covered.
If you only have raw pepitas, then place on a tray, spray with olive oil and cook in the oven at 150°C/300°F for 20 minutes. Once cooked, crush with a mortar and pestle.
Cut up the onion and garlic and cook until slightly brown on a low heat
Put all ingredients in a bowl and blend
If the hummus is too thick after blending, keep adding 1 tbsp of olive oil and 1 tbsp of water until it gets to the desired consistency
