Monstrous Mash

Recipe by GT in SA

Mashed potatoes have as many guises as there are cooks. We had this one with grilled fish and coleslaw. Salivate away!

What a find - mashed potatoes so good no one misses the gravy! Made as posted. I was a little hesitant when it came to the 2 tablespoons of white vinegar but followed through, used the English mustard and spring onions - it all came together resulting in a potato dish looking as good as it tasted! Thank you GT, definitely a repeatable.
