1. Put the chickpeas, lemon juice, tahini, cumin and garlic into a food processor and pulse until smooth. With the motor running, slowly pour in the oil in a steady stream. Add the salt and puree until very smooth. If the mixture is too thick, add some of the reserved chickpea liquid, 2 tablespoons at a time, until the desired consistency is reached.
2. To serve, transfer the hummus to a serving bowl and drizzle some olive oil over the top. Garnish with a sprinkling of smoked paprika if using, and serve with vegetables and pita chips for dipping.
Store leftover hummus in an airtight container in the refrigerator for up to 5 days.
