From my mom...
Here's the recipe: 2 sticks of butter; 2 packets of yeast; 1 Liter of milk; 1 cup of raisins; 5 Lbs. of flour.
Warm the milk, take 1/2 cup warm milk and mix the yeast, melt the butter. In a bowl put all of the said ingredients then start adding the flour, I use up half of the bag, so it is about 2 1/2 lbs of the flour. If the wooden spatula can stand that means the mixture is good.
Cover and let it rise for 1/2 to 45'. The raisins I mix a little flour then once the mixture is fully rised add the raisins.
You need 4 foil bread tray. Fill it up with the mixture about half full.
Bake in a preheated 400 degrees oven for 45'.
