When I first began uni, ‘mash up’ was the term used to describe partying and mashed potato. A weird combination; however, mash was very often consumed on a Friday night before going out partying and eaten with lots of mates, beer and wine. You can add just milk, cream and seasoning to it, but you could also add mustard, pesto, garlic, peas, apricots, rosemary, or cheese. It’s so versatile, just remember to season well.
