Zwiebelfleisch
Zwiebelfleisch is an old Viennese Beisl dish, the kind of hearty lunch an inn serves on a cold weekday, with boiled or fried potatoes alongside. Thin slices of beef braise slowly with a mountain of onions, a splash of vinegar, caraway and marjoram until the onions melt into a sweet, tangy gravy. The usual mistake is browning the onions too fast: they turn bitter, so let them colour slowly to a deep gold. Pressure-cooker: 25 minutes at high pressure after browning. Chef's tip: a teaspoon of mustard stirred in at the end rounds out the sauce and brightens the vinegar.
