The reason I've taken a star away from my rating is that I changed the recipe considerably.
I didn't want to make such a lot of spätzle, so I cut the recipe in half, approximately - 2 cups of flour to four large eggs (also salt, nutmeg and white pepper). I chopped up 4 slices of thick cut bacon and an onion to fry up in butter to sauté the spätzle in afterwards, which came to three batches in my big pot of boiling water.
I'm figuring that the complaints about the blandness of this dish come because of the relatively small amount of sauerkraut - I used this half recipe of spätzle with the same amount as given here. Mixed it all up in the pan and fried it together for a few minutes until all piping hot, then served with grilled bratwurst. Lovely!
