"Skordalia", the greek puree

Find today a different way to make a potato puree, the greek way :) that has (what else?) olive oil and plenty of garlic. Beware, no romantic evenings that day ;)
Ingredients
4 potatoes
2 spoonfuls of apple vinegar
1/2 cup of olive oil
5 garlic cloves
some salt


Procedure
Boil the potatoes with the skin for about 30min or until they are soft enough (use a knife to test).
Then, peel off the potatoes and smash them slightly using a mixer. Add the salt, the smashed garlic and while mixing them, add little by little the olive oil until it gets a nice soft and glossy texture.  
Use it as a starter or to accompany meat or fish. Great combination is a traditional Greek dish that is called "mpakaliaros skordalia" that is actually fried cod fish with "skordalia" usually made on 25 of March, national day for Greece.
