Preheat an oven to 160° C - 320° F.
Spread the individual unpeeled garlic cloves in an even layer across an oven tray. Coat evenly in olive oil and salt generously.
Roast the garlic cloves until they have gone soft and squishy, in my oven this takes about 30-45 minutes.
Drain the soaked chickpeas, place them on a kitchen towel and dry them off gently.
Move the chickpeas to a heavy-based pan with the baking soda and cook on a low heat while stirring vigorously for 2 to 3 minutes or so.
Cover the chickpeas until they are submerged in about an inch of cold water and bring to a boil.
Leave to simmer until they are soft. This should take 30 minutes to an hour, depending on the quality and age of your chickpeas. Use a ladle to remove any foam or chickpea skins that come bubbling to the surface. Add water if your chickpeas appear to be drying out, but haven't softened yet.
Drain the chickpeas, making sure you hang on to the cooking liquid. You'll need it for the next step.
Peel or smoosh the garlic out of their skins.
Place the chickpeas,1/4 c - 60 ml olive oil and garlic mush into a food processor along with a first scoop of the cooking liquid. Blitz for 2 minutes. Add more of the liquid if your food processor starts to struggle.
Finally add 1/4 c - 60 ml lemon juice, 1 t - 5 gr salt, 1/4 t - 1.5 gr cumin, 1/2 c - 120 ml tahin, 1 T - 15 gr miso and 3 ice cubes and blend again for at least 2 minutes until well combined and fluffy. If your food processor is struggling again use a wooden spoon to beat the ingredients together until the last of the ice cubes as dissolved completely.
