1 can (15 ounces) chickpeas, rinsed and drained
½ teaspoon baking soda
¼ cup lemon juice (from 1 ½ to 2 lemons), more to taste
1 medium-to-large clove garlic, roughly chopped
½ teaspoon fine sea salt, to taste
½ cup tahini
2 to 4 tablespoons ice water, more as needed
½ teaspoon ground cumin
1 tablespoon extra-virgin olive oil
Place the chickpeas in a medium saucepan and add the baking soda. Cover the chickpeas with several inches of water, then bring the mixture to a boil over high heat. Continue boiling, reducing heat if necessary to prevent overflow, for about 20 minutes, or until the chickpeas look bloated, their skins are falling off, and they’re quite soft. In a fine-mesh strainer, drain the chickpeas and run cool water over them for about 30 seconds. Set aside.
Meanwhile, in a food processor or high-powered blender, combine the lemon juice, garlic and salt. Process until the garlic is very finely chopped, then let the mixture rest so the garlic flavor can mellow.
Add the tahini to the food processor and blend until the mixture is thick and creamy, stopping to scrape down any tahini stuck to the sides and bottom of the processor as necessary.
While running the food processor, drizzle in 2 tablespoons ice water. Scrape down the sides, and blend until the mixture is ultra smooth, pale and creamy.
Add the cumin and the drained, over-cooked chickpeas to the food processor. While blending, drizzle in the olive oil. Blend until the mixture is super smooth, scraping down the sides of the processor as necessary, about 2 minutes. Add more ice water by the tablespoon if necessary to achieve a super creamy texture.
Taste, and adjust as necessary then top with garnishes of your choice, and serve. Leftover hummus keeps well in the refrigerator, covered, for up to 1 week.
