Sauce:
Put the milk and eggs in a blender. Once mixed, pour into a bowl and add the flour and teaspoon of oil. Mix thoroughly.
Heat a bit of oil in a pan (hopefully a Teflon pan). Pour some of the mixture until the whole diameter of the pan is covered. Then brown both sides, take out, and allow to cool.
For the sauce, mix all the ingredients in a medium pot, and cook over high heat until it comes to a boil. About 5 minutes. After that, lower the heat so that it boils softly, and simmer for about 20 minutes, until it slightly thick.
Stir once in a while and allow to cool. Pour over the crepes.
