I don’t use them a lot, but they are super handy to have for doughnuts and scotch eggs for example.
If, like me, you don’t have much space and you rarely deep fry anything, the below deep fryers are perfect - I’ve owned 3 over the years and they are cheap, reliable and can fit two mini doughnuts at a time, a small portion of chips, paprika pork puffs (see here for recipe: Paprika pork puffs recipe), or a single scotch egg!
