Cook the potato with a ham hough or some bacon in the water for a meaty flavour. Cook for 10 mins then add the tatties. Drain and save the water 7 meat for a soup.
Make mash with sour cream. Make with olive oil or infused oilve oil - chili, hebs, garlic etc.
Add some chopped herbs, add rosemary (spairingly as its strong), add some stock powder to the mash, add gravy granules, add sauerkraut, add finely sliced fried cabbage - red, white or green variety, add a mix of other cooked veg - carrot, swede, turnip.
Use sweet potato instead, or yam or celeriac.
Keep the skin on to retain the vitamins and minerals - boiling reaaly reduces the goodness. Cut the potato into small chunks to cook if mashing in the skin.
Add horseradish, add grated cheese, add chipotle chili for a smoky flavour, add finely diced cooked smoky bacon or some cooked sausage meat, onion and gravy- and call it stovies . .
Make too many for one serving and use the rest for a breakfast fry, or make up as a potato loaf, or as champ, or boxty, or rumbledethumps or bubble & squeak or fish cakes or as a topping for fish pies etc.
