This recipe is all about the mushroom sauce and as the title suggests I use it to make Jägerschnitzel, a schnitzel with hunter sauce. I won't repeat how to make schnitzel here and will focus only on the mushroom sauce (mushroom gravy).
This is a easy recipe and doesn't require pan dripping or juices so is well suited for vegetarians (simply swap the beef stock for vegetable stock). For a far richer mushroom sauce for steak which does require a little more effort try the Mushroom & Red Wine Gravy recipe.
For this recipe I use basic white button mushrooms, of course you can use any mushroom or a mix of mushrooms you wish as the base. Portobello work well, as do a mix of swiss brown and shiitake mushrooms, whatever is in the fridge or whatever is your preference. You can also play around with additions such as bacon or pancetta and you can add a little extra onion if you wish.
The sauce is very versatile and can be used for steaks, bangers and mash or to drown your chips in for a wickedly indulgent chips and gravy, if that's your thing.
Not really much else to say other than, have a go and let me know.
