From my childhood I remember eating sauerkraut with only potatoes and grease... Not so fancy, and really NOT loving it!
Until my mom discovered a different way of serving it and since then I've been enjoying sauerkraut more and more.
Watch and learn to prepare sauerkraut the way my mom has learnt me.

Step 1: What You Need for This Dish:

1 a package of sauerkraut contains 0,5 kg
2 bags of instant mashed potatoes (per bag you need to add 0,5 liter boiled water
3 1 large hand of raisins
4 butter to grease the dishpan
5 1 can of pineapple pieces (also about 0,5 kg)
6 1 smoked sausage
7 curry powder

(these are the packages as they are available in the Netherlands, try to get about the same content if you use other packages)

Step 2: The Sauerkraut:

Open the can with pineapple pieces and pour the juice in the small pan.
Add the sauerkraut, and put the pan on the stove.
Once the juice/water boils put the stove on low heat and let it boil for 5 min.

Step 3: The Mashed Potatoes:

In this case you need to add water ánd milk according to the package of the instant version.
Since I am allergic to milk I only add water, the same amount as the milk and water would be together.
So I boil 1 liter water and add half of it to my measuring bowl.
I add the instant powder, mix and let it sit for a while.
In the mean time I grease the dish pan.

Step 4: The Smoked Sausage:

I don't know if you ever had a change to eat it but I love it!
Especially the ones HEMA sells, so if you visit the Netherlands you definitely need to visit a HEMA for their ROOKWORST.
Of course this sausage doesn't taste the same, but is also very good.
I slice it the way the picture shows and usually end up eating the leftover part....

Also pre-heat the oven at 180 degrees Celsius / 356 Fahrenheit.

Step 5: Filling the Dishpan:

1st layer: mashed potatoes
2nd layer: sauerkraut, pineapple pieces and raisins
3rd layer: mashed potatoes
4th layer: sliced smoked sausage & curry powder

About the 2nd layer:
Once the sauerkraut has boiled for 5 min. I pour off the juice/water it boiled in and pour it in the measuring bowl. I add enough water to get to half a liter and make the second bag of mashed potatoes with it.
