Oooh I love making hummus! It's so much cheaper, tastier and more versatile than buying it from the shop. The above recipe is a great starting point - you can tinker with the quantities to suit your taste! I personally love it strong, with lots of garlic, lemon and black pepper. I would also include the oil in the blend rather than on top.
For even more variety, try blending in small amounts of roast red peppers, sundried tomatoes, olives, chilli peppers, the list is endless! Enjoy x
