Chiming in here when it's all about the
Wiener Schnitzel...
The real Wiener Schnitzel should definitely be made with veal and pan fried in clarified butter (or lard which I don't particularly like but others do). Both adds so much flavour and really turns it into a treat.
Most places make it out of pork meat, though, and deep fried in cheap sh*t. While that still creates a feeling of satiety, there is not much pleasure involved during its consumption. Cheap will probably cost half of the real thing. But the real thing is worth every penny.
Some add a slice of lemon, either squeeze a bit of its juice over the Wiener Schnitzel, or cut off a piece and press on the lemon slice for a moment. Some eat it with cranberry/lingonberry jam. Sides include potatoes with parsley and/or different types of salad (green, cucumber, potatoes), nowadays even french fries or rice. Ketchup? I clearly say, "No. Never. Ever". But if you're a ketchup person and need to make everything taste like ketchup, then please, for G**'s sake, only do it with the pork version. BTW, the pork version shall not be called Wiener Schnitzel, but rather "Schnitzel Wiener Art".
And to all my German friends: ONE DOES NOT ADD ANY SAUCE TO WIENER SCHNITZEL.
