The potato salad tasted pretty good last night. I considered also eating it for breakfast this morning. But I managed to wait until lunch. And it really is much better the next day. Well, it doesn't have to be the next day - at Christmas Mum usually makes it in the morning and it's great by lunch time. I think the sour cream and the other parts of the dressing need a little time for the flavours to combine fully.
I had to improvise the potato salad from memory last night - I know I've copied the recipe before but I don't know what happened to it. I dropped round to see my parents this afternoon and copied it again. Mum cut it out from a magazine many many years ago, so I don't think there should be any problem sharing it here.
Sour cream potato salad
The introduction to the recipe claims this is a German style potato salad.
6 medium potatoes
1 medium onion, finely chopped
1¾ cups beef stock (I use vegetable stock)
4 tablespoons white vinegar (apple cider or other vinegar of your choice works too, perhaps not balsamic though!)
5 tablespoons salad oil
2 teaspoons prepared mustard
white pepper and salt
½ cup sour cream
Cook unpeeled potatoes in boiling salted water. (We steam them). Do not overcook or they will not keep their shape in the salad. Peel the potatoes while still hot (we don't bother) and cut into slices. Place in a bowl with the onion.
Bring the stock to the boil with the vinegar added, and while boiling pour over the potatoes. Marinate until almost all the liquid is absorbed, about 20-30 minutes. Pour off any excess liquid (this might depend on the type of spuds - I had to pour off a lot of liquid) and gently fold in the oil mixed with the mustard.
Taste, and season with white pepper and salt if necessary. Lastly, fold in the sour cream. Serve at room temperature, garnished with parsley or other fresh herbs. (It's perfectly nice refrigerated too, if you are concerned about leaving food in the 'danger zone' temperature-wise.)
Serves 8-10 (Ha! Not necessarily)
Update in response to some comments:
Salad Oil: I always though 'salad oil' meant a simple oil-based dressing like French or Italian. When I looked it up, most sites said it is simply any oil that can be used in salad dressing. Which makes sense for the recipe as you can season it separately and it is also already strongly vinegar-flavoured so you wouldn't want to use a strongly vinegar-y dressing. Though I personally have a huge appetite for vinegar, I know some don't like it too strong.
Raw onions: I never eat raw onions as I hate the way the taste stays with me for so long. I find they are blanched enough by the boiling stock marinade that they are ok in this recipe. However, I have also used shallots (green onions/spring onions) which look nice and taste milder.
