Add the chickpeas, the garlic, the tahini, lemon juice and sea salt, and blend on high speed until the mixture is creamy and smooth.
While the food processor is running, drizzle in the olive oil until the hummus becomes even more creamy and pale in colour. Add up to 3 tablespoons of water, only if necessary to thin out the hummus.
Serve immediately with your favourite veggies, pitas, crackers or chips, or store in an airtight container in the fridge until ready to serve.
Notes
This hummus keeps well in the fridge in an airtight container for up to one week, and in the freezer for up to 3 months.
