Put the dry chickpeas in a medium bowl with 1/4 tsp baking soda and fill with water to soak. Leave to soak for 6+ hours or overnight.
Drain the chickpeas and place in a medium pot with another 1/4 tsp baking soda. Fill with water. Bring to a boil, then reduce to simmer. Let simmer for 1 hour until the chickpeas become soft but not mushy.
Once done, strain your chickpeas and let sit to cool off completely.
Once cooled, add the chickpeas to a food processor, along with the tahini, lemon juice, garlic, cumin and salt, blend until smooth.
If the consistency is too thick, add a dash of cold water, only a little at a time until a desired consistency has been met.
Store in a sealed container in the fridge for up to 1 week.
