  1. Just tried this sauce and I simply wanted to lick the plate! We made it with chicken stock and didnt need the xantham gum it was fab as it was. Thanks for sharing this recipe 😊

  2. I made this tonight have made before but without the can’t xnathum gum but added it tonight what a difference !! so so tasty whole family loved it will definitely make again.

    1. Hi Sharon
      It’s just 3 average sized (probably medium sized) closed cup mushrooms. You of course add more or less according to taste

  3. I have no idea what the gum is, never seen it in any Uk shops. So i tied it without and it was watery, the quark curdled and split and we had to throw it out. Hmm

    1. Hi Lesley
      You can find Xanthan Gum in the Free From aisle in most supermarkets (Asda definitely sells it). As well as thickening it stabilises sauces so they do not split when heated, which makes it ideal for sauces containing quark or yogurt

  4. I got a pot of the Xanthan Gum from the internet. It woukdnt mix so I could see tiny white bits. Then I have tried to mix it in cold liquid, lumpy again. What am I doing wrong???

  5. I’ve just made this sauce but substituted the Worcester sauce for mushroom ketchup, delicious!!! Fabulous recipe thank you 😊

  6. Have bought some Xanthin Gum to try this sauce but I am a little confused over the quantity – is it three quarters of a teaspoon of 3 to 4 teaspoons? Likewise with the onion – half an onion or 1 to 2 onions please?

    1. Hi Shirley
      Yes it should be fine to freeze as it contains xanthan gum, which as well as being a thickener also acts as a stabiliser which stops things splitting and curdling during cooking and freeing

  7. Is it me or is there no actual mention of ‘pepper’ in the ingredients for this? Is it made using standard white or black pepper or actual peppercorns? And how much? Thanks

  8. We made it last night and it is lovely.
    Looking forward to more recipes with the Xanthan gum – it really transforms it.
    We’ve found a lot of SW recipes use fromage frais/greek yoghurt and I find they taste horrid because of it. Quark and Xanthan gum all the way 🙂

  9. Here’s what I just tried. 1 small onion chopped up, 300 grams of mushrooms chopped, 1 Oxo beef cube in 200 mill water and half a garlic clove crushed. I fried it all until nice and reduced and soft in fry light. Then added the frying pan contents into the jug of beef stock then I blitzed it to a smooth mix with hand blender. Then I added about a tablespoon of crushed peppercorns then mixed these in to the sauce. I left it to cool down to warm to touch. Finally I added 2 tablespoons of zero fat Greek style yoghurt. I’ve got to say this was as good as any peppercorn sauce I’ve had. To prevent splitting you simply just have to add it to anything once it’s cooled down to warm. Then reheat it in microwave and it doesn’t split.
