Tins of corned beef are often available from community larders – this is a really simple recipe to make use of them. Like me, you might have been wondering what corned beef is and where the name comes from – after all it doesn’t contain corn. Corned beef is beef (usually brisket) preserved with salt using a process called ‘curing’. The large grains of salt used were known as ‘corns‘ in Old English.
This dish also uses quite a few fresh potatoes, which are one of the three most commonly wasted foods in UK homes. Alternatively, you could use leftover, frozen or even powdered mashed potato.
This is the perfect recipe to experiment with substituting ingredients. If you are short of potatoes, throw in any other starchy root vegetable. Sweet potato, swede, turnip and even carrots or parsnips can all be mashed – I like to use a combination. I’ve even seen a recipe that used half potato, half cauliflower.
If you run out of frozen peas, try adding frozen or tinned carrots or sweetcorn. This might divide opinion, but I actually love adding a tin of baked beans to these kinds of meat (or substitute) and mash dishes. Give it a try – let me know what you think.
If you only have one tin of corned beef or want to reduce the fat and salt content, swap out half the beef for fresh or tinned mushrooms. Pre-cooked or canned lentils would also be a good choice as they are high in protein and fibre, but low in fat.
Of course, this isn’t one for anyone following a plant-based diet, although you could use a meat substitute or a mix of pulses and finely chopped or grated to veg to make a similar dish.
