As i'm a haphazard bit of this bit of that bit of whatever in the kitchen i can't give you exact quantities, escpecially as i say 'it's made to taste'.
I just cook up 6-8 medium-large size spuds until they're soft enough to poke a fork into but not crumble, IYKWIM. Then of course let them cool for min 30 mins or you'll find it ends up a bit like mash.
Mix in a tub of mayonnaise (coles brand goes just fine, but if you get something like kraft, it does have a richer, smoother taste to it).
Mix in half a jar of Masterfoods Honey Wholegrain Mustard. It a) gives a nice flavour b) gives a bit of colour.
Dice as much spring onion to your desire.
And if throwing in some sliced boiled eggs takes your fancy it's also a nice touch.
Mix it all together!
