Potato salad can be very delicious when its done correctly.
I know two different variants
First:
cook the waxy potatoes and peel them
let let them cool down a little
slice them into a bowl
hash the peeled onions
wash the parsley and also hash it (without stapes)
put all to the potatoes
heat the bullion and douse the potatoes with it
they now should be a bit wet.
cover the bowl with the ingredients and let it pervade for at least one hour
put oil and viegar on the potatoes and carefully mix it all
flavour it with salt and pepper
serve
and just pulpify the potatoes if you really like it that way
Second:
You need also waxy potatoes
cook and peel them
use vinegar and salt to add some seasoning.
let them cool
and slice them into ab owl
put pepper and if needed salt to it
mix it a little.
add mayonnaise and yogurt
also a bit mustard and horseradish
optional add diced: gherkin(pickled and/or not pickled), radish(garden), chive, apple, roasted beacon
mix carefully and serve
I mean seriously, potato salad with smashed potatoes is really something where you need to get used to.
