Tried your suggestion of Branston sauce as a substitute of the now crap HP, fantastic, better than HP was to start with I think.
I'm trying to find Dave's suggestion of the HP with Guinness. I'm sure I've seen. It in our Tosco but it's not there lately, probably didn't sell enough, maybe they should mix it with Jagerbombs instead then the sods round here would buy it.
Bugger, forgot about the mushroom sauce and I recognise that bottle. I couldn't get the Branston in our local Tesco, I only noticed it in Morrisons this morning by chance.
