German dark beer gravy

A sauce evoking the atmosphere of Bavarian beer gardens, where the caramel sweetness of malt meets savoury roast juices. This is not a quick dressing, but a deep-flavoured companion based on reduction, with the bitterness of beer providing the backbone. In German cuisine, 'Biersauce' is sacred: a mandatory element for pork knuckle or a fine bratwurst, connecting the meat with the side dish.

Instructions

1

Dice the onion very finely and crush the garlic. Have the stock and beer ready to hand.

Tip: The smaller the onion, the sooner it cooks down in the sauce, preventing a lumpy result.
2

Melt the butter in the saucepan over medium heat, then add the onion. Sauté until completely soft and translucent, and edges start to brown.

Tip: Caramelisation of the onion provides the foundation. If it browns too fast, lower the heat; black onion is bitter.
3

Toss in the crushed garlic, stir once, then sprinkle with the flour. Stir constantly for 1-2 minutes until the floury mass turns biscuit-coloured.

Tip: This is called a roux. The flour must be 'toasted' to lose its raw taste, but careful not to burn it.
4

Pour in the dark beer whilst whisking wildly to prevent lumps. Let the beer foam settle and the liquid start to thicken.

Tip: The alcohol content evaporates now, leaving only the malt flavour.
5

Add the beef stock, mustard and brown sugar. Mix until smooth.

Tip: Brown sugar helps counterbalance the hoppy bitterness of the beer.
6

Simmer gently for 10-15 minutes until thickened into a dark, glossy sauce. Season with salt and pepper at the end.

Tip: It is ready when the sauce flows silkily off the spoon, not dripping like water.

Recipe FAQ

Which beer should I choose?
Definitely a dark beer or Dunkel. Stout type beers (e.g. Guinness) can be too bitter, whilst light beers don't provide enough depth.
The sauce is bitter, what did I do wrong?
You likely burnt the onion or reduced the hoppy beer for too long. A little extra brown sugar or cream can help dampen it.
