In the UK, baked beans.
In my work we did a blind taste test of 10 different brands of baked beans, with participants ranking them in order from best to worst. The name brand options such as Heinz, HP, and Branstons ended up in the middle, with the cheaper options from Aldi and Asda being the best. The most expensive beans were from Marks and Spencer and were voted the worst ones.
If you're paying more than 50p a can its not worth it.
