Method
Prep:5min  ›  Cook:30min  ›  Ready in:35min 

1. Dice the onion then fry in a small saucepan until soft, in a small amount of oil.
2. Cover with water (you don't need much, just enough to cover it, and crumble the oxo cube into the mixture.
3. Bring to a simmer and reduce down until almost all of the water has gone, normally about 30mins but depends on quantity.
4. You can now either progress straight to the next step or leave the sauce to stand, allowing you to make it ahead of time. If you prepare it ahead then just place it in the fridge until 5 mintues before you need it.
5. Place the sauce on the heat and add 1 tablespoon of white wine vinegar and a small amount of mustard powder (literally enough to cover your little fingernail).
6. Heat the sauce through for a couple of minutes then serve.
