A holiday recipe for you all: Czech potato salad.
This salad is made 24 hours in advance of Christmas dinner (had on the 24th here, so the salad is made on the 23rd). Everyone loves it, so it's always necessary to make loads and loads of it so it can be had for leftovers for the rest of the week.
For a standard batch (which is quite large):
Boil ~1kg whole, unpeeled potatoes in salted water until soft. Set aside to cool.
Boil ~1/4 kg peeled carrots, parsley root, and celery root in salted water with a bit of vinegar, until mostly soft.
Hard boil 3-4 eggs.
Peel the potatoes and dice them into very small cubes, about 1 cm on a side. Dice up the other root vegetables as well, in very small pieces. Do the same with about 3 sweet pickles/gherkins, a few TB of red onion, a hunk of smoked ham (up to you how much you want in there, can be left out for vegetarian version), and the eggs. Add a handful of peas (defrosted if frozen, strained if canned). Mix together in a bowl with a few scoops of mayonaisse and a few spoonfuls of the pickle juice. Add a bit of salt and pepper if desired.
And now, the most difficult part: wrap it up and leave it in the fridge for 24 hours. It is well worth the wait.
This is traditionally eaten with fresh fried carp (which is DISGUSTING), or for those who aren't hardcore enough to bear the carp, salmon, fried chicken, or other substitute. The potato salad is almost exclusively made for Christmas, but there's really no reason not to make it all the time. It's pretty amazing. Every family has a slightly different recipe, so feel free to adjust this one as you see fit.
