Bangers and Mash is the familiar term for Sausage and Mash, a favorite British and Irish dish. The name bangers is believed to come from the habit of sausages bursting in the pan with a bang if cooked too quickly.

Bangers and Mash is quick and easy to make, and also makes a cheap yet very substantial meal. A great favorite with children.

Where once it was only possible to buy beef or pork sausages, there are now many different flavors available, from spicy through to fruity.

  • When making your mashed potatoes, make sure that you cut your potatoes into even-sized pieces so that they all cook at the same rate.
  • Put all of the potato pieces in a pot with cold water, bring to a boil, then reduce to simmer until fork tender. The fork should be able to easily pierce the potato without effort.
  • To warm ceramic plates for serving, stack them in an oven for 15 minutes at the lowest possible temperature - like 150 F. Make sure that you use oven mitts when removing the plates from the oven, as you don't want to burn yourself. Also, inform others that the plates are hot.
