This recipe comes from my great grandmothers from Austria. Growing up this was how our spinach was always served and still is to this day. Kids who normally will not touch spinach on their plate will surprise you normally by eating this one! My son is not a spinach lover at all, but will eat spinach as long as its cooked like this.
Boil spinach and drain reserving some of the liquid.
Dice Bacon and cook until nicely browned.
Add flour to the bacon drippings. Stir and cook a few minutes.
Add spinach and a little reserved liquid to the bacon and spinach mixture. Cook until creamy. If the mixture seems to be too dry (not creamy) add a little more reserved liquid (a little at a time) until it gets creamy.
