In the bowl of a food processor, combine the tahini and lemon juice and process for 1 minute. Scrape the sides and bottom of the bowl, then process for 30 seconds more, making the hummus smooth and creamy.
Add the olive oil, minced garlic, cumin and a 1/2 teaspoon of salt to the whipped tahini and lemon juice. Process for 30 seconds, scraping the sides and bottom again, then process another 30 seconds or until well blended.
Open, drain and rinse the chickpeas. Add half of the chickpeas to the food processor and process for 1 minute. Scrape the sides and bottom of the bowl, then add the remaining chickpeas and process until thick and quite smooth for 1 to 2 minutes.
Most likely the hummus will be too thick or still have tiny bits of chickpea. To fix this, with the food processor turned on, slowly add 2 to 3 tablespoons of water until you reach the perfect consistency.
Taste for salt and adjust as needed. Serve hummus with a drizzle of olive oil and dash of paprika. Store homemade hummus in an airtight container and refrigerate up to one week.
