Home made food or ingredients not worth the effort

[yeager2004]

While it’s all very virtuous to make everything in the kitchen from scratch, over the years I’ve concluded that for the effort involved against the improvement in taste, a number of things are not worth the effort.

A few examples of things I’ve tried making, and will not bother in attempting again include:

Puff pastry
Peanut butter
Imitations of biscuits e.g Jaffa Cakes
Roasting green coffee beans
Curry paste
Pasta

Needless to say, this may be down to my ineptitude. What other examples do you have?
