I agree with Kitov. I have done it myself numerous times (a habit I picked up from Israel). It is sure more cost-effective unless you just use a small amount.
All you need is a 1/2 pkg of Garbanzo/Chickpea beans (or a can or two – is much easier), Techina paste, fresh squeezed lemon juice, fresh crushed garlic, olive oil, water and salt.
Store bought have all that preservatives plus etc.
RY, you can use a hand blender as well. And you are Yotza your deed of ‘Lekavod Shabbos’ preparation.
