Mash is pretty traditional fare here in the UK and it was one of the lads favourites as they were growing up. I always liked to add something extra to change the flavour around a bit (and get some extra nutrients in). This could be...
- sweet potato
- butternut squash
- cooked savoy cabbage, finely chopped
Although I generally mash with butter, I also sometimes add olive oil for a slightly different flavour. I also add herbs and plenty of black pepper.
This is free style cooking, the amounts vary depending on the contents of my fridge.
