Caveats: Home made food is usually:
A. Nicer
B. More nutritious
C: Made with proper ingredients that you can control
D: More filling
E: Not made with fillers, starch etc
But it's not always cheaper!
Time after time, when people post about food costs, the trope is always make it yourself, you'll save money. This post is in frustration after yet again, someone tripped it out on a budgeting forum. Someone commented that Tesco budget hummous is quite nice, to be told, as always, you can make it cheaper yourself.
You can't. Eastman's hummous 69p
Tesco chickpeas 60p + lemon 30p = 90p and that's before you add olive oil and tahini.
Yes I know you can soak your own chickpeas and buy in bulk at an Asian grocer etc, but that level of organisation for most people is beyond the effort of just picking up a tub on the weekly shop.
For the record, I am a very keen home cook and have also run a food business and written about food in the past. I enjoy cooking, but I am sick of people trotting out this line without thinking about it, especially on budgeting and money-saving forums.
