Amy's been wanting me to try this for some time and I finally got around to it the other night, basically it's a stuffed potato hors d'oeuvres that was jolly tasty.  What you stuff it with is really up to you, but the basic starter point is the potato.  Top and tail them to give them a nice flat surface to work with then using a melon baller core the potato to leave a hollow shell.  Dump them into boiling water for 10 or so minutes, checking with a sharp knife to check their doneness.  When finished with that coat them in olive oil and throw them into a 400f oven for ten minutes to give them a crisp and then (assuming your filling is cold) let cool. 

In this case my filling was a bit of salmon tartare.  Minced shallots, chopped smoked salmon, chopped capers, in one bowl.  Creme fraiche and a tea spoon of lemon into another bowl - whisk the creme fraiche until you get some stiff peaks then mix the salmon mixture in with the creme fraiche.  Top with a touch of cavier, a little chive and serve with a nice chilled savignon blanc.
