Vinnie's Mash Potato Recipe

500gm Floury potatoes (in New Zealand I'd use Agria) 300ml single cream 200gm butter salt nutmeg butter to finish

 

1. peel and cut the potato in 3cm dice
2. bring to the boil (just covered) in heavily salted water (slightly less than the sea)
3. strain as soon as you can easily poke a sharp knife through them 

(if they over cook and take on water they will be too salty)

1. once fully drained put them back in the pot on a low heat until the outside is fluffy and dry
2. meanwhile in another pot start reducing the cream and butter until it takes on the consistency of thermal mudpools bubbling. In NZ it would be quite yellow at this stage but our cows are grass feed.
3. while this is happening, force the potato through a sieve or ricer, working the potato as little as possible
4. Now whip the potato's in to the cream mixture, this should almost immediately come cleanly away from the sides of the pot and be ready to serve.
5. Spin the pot to make a ball, tip into a bowl, sprinkle with nutmeg and stick a 1cm knob of butter in the middle 

Maybe mash potato seems like a lame recipe, but this method produces the best results, I think.

p.s. water is the enemy of mash potato. Water out--Fat in
