Wash potatoes thoroughly, sprinkle a little with olive oil - and on a baking sheet.
Bake for 30-40 minutes until Golden brown. Once during this time, the potatoes need to turn - to evenly covered with a crust.
Mix mustard, mayonnaise and olive oil.
There same add crushed garlic and lemon juice. Salt and pepper, mix until smooth.
Peel and cut the potatoes into quarters or halves, depending on the size of the potatoes. If the potatoes are very small, you can put the whole. The original recipe uses young, small potatoes, which are not cleaned and put whole. Pour the sauce over the baked potatoes. Thoroughly. Ready! Serve cold.
