The order is important – it doesn’t turn out well if you do it in the wrong order.
Weigh 140g of tahini directly into the food processor bowl – less mess that way.
Squeeze the lemon juice until you have the 140ml – and pour into the processor bowl
Blend the lemon juice and tahini for 60 secs (can do longer it’s not critical just needs to be well mixed).
Add in crushed garlic, sea-salt, olive oil and cumin if using.
Blend for another 60 seconds scrape and blend for a further 60 seconds (or until very smooth). Again – can be longer.
Add both lots of chick-peas, and blend for 5 minutes – if you use frozen chick peas, there's generally no need to scrape the sides etc as the frozen chickpeas do it. Check to see how well it's blended.
I love it extra smooth so I do it for even longer. However you don’t want it to get warm as this will alter the flavour. A trick here is to use the frozen chick-peas – so that the hummus doesn’t warm up in the blender! Use ear defenders though as it’s very noisy! Using ice cubes for the extra water content helps too.
Towards the end, you can dribble in some chick-pea juice if you have it or just water until you get that creamy (but not runny) consistency. Bear in mind it will thicken up in the fridge if not used immediately, so to maintain the nice creamy texture you will need to mix in extra water/ice cubes
