*if you prefer garlic in your hummus, I rec just a tiny amount. 3g or the smallest clove you can find. For me, it wasn't needed in this recipe.
Add the beans to a tall container, add 2qt water, stir, and allow to soak overnight. After soaking they should have nearly doubled in size.
Add soaked beans and water into a pressure cooker along with baking soda. Cook under high pressure for 90 minutes then allow pressure to release for 20 minutes. Beans should be soft but not disintegrated.
Drain off as much cooking liquid as possible then transfer beans to a food processor along with tahini, salt, lemon juice, and citric acid. Process for 3 minutes then stream in olive oil while still spinning.
Add ice cubes into food processor one at a time until hummus reaches desired texture/consistency.
Taste for seasoning and add extra lemon juice, salt, and/or olive oil if needed.
Spin for a few seconds to combine.
Serve with olive oil, a sprinkle of sumac, and flaky salt.
