Combine Milk and yeast with Vanilla Sugar and a few tablespoons of flour in a bowl. Let sit for 5 minutes. Then add flour, eggs and a bit of salt. Mix well, and let the yeast activate for 10-15 minutes.
Add the Raisins, mix in well.
Add enough oil to a frying pan to cover the bottom with maybe 1/4 inch. Heat it up.
Add batter (it will be sticky) to the oil by the ladle full.
When it browns on the bottom, flip it over.
When both sides have browned... put the Struwen on a rack covered by a paper towel.
Sprinkle with Sugar or Cinnamon Sugar.
Serve them Warm!! (You can eat them cold, they just aren't as nice).
