Reserving the liquid, drain 1 16 ounce can of chickpeas, and rinse under running water. Any skins that may come loose can be removed. Put the drained chick[eas in the bowl of a food processor.
Put the garlic cloves, tahini, 2 tablespoons of the olive oil, and the salt in the processor.
Using a wooden reamer, remove the juice and the flesh between the membranes from the lemons. You want at least 1/3 cup of lemon juice, or more if you are very fond of lemony hummus. Add to the food processor.
Process everything until you have a texture that you like. You can add some of the reserved liquid from the can of chickpeas to thin it out a bit. Process a few minutes more, after adding the reserved liquid.
Add in whatever extras that you like, and blend well.
Scrape the finished hummus onto a flat bowl or plate and swill around a bit so that it looks appetizing. Chill for at least a couple of hours. If serving later than the same day, put the hummus in an airtight container to refrigerate, and spread it on a plate when ready to serve.
When ready to serve, drizzle the remaining olive oil over hummus and sprinkle some paprika, cumin, and or chopped herbs over the top.
Serve with pita breads, pita chips, veggie sticks, or use a spread for sandwiches.
