Wow Biz..semi chewable Guinness..
It sounds extremely odd...!
I give most foods a go..
If someone else eats it then I'll try it..I'm not too fussy
I like to be adventurous. ..
Does not sound like my cup of tea though as I don't like Guinness.
But I would try a little plug of it...
sauce keeps well in cupboard for a few months probably..
if you sterilise your bottles and add when hot.
once opened keep in fridge. Seems to keep well..no time limit as we seem to get through it before anything seems to happen to it...mold or going off etc..
it's quite moreish!
Always give a few bottles away too.
we call it Partyleg Sauce after I made it after a party first time..
Friends are always asking when I'm going to make it as they love it as much as me.
I hope you guys try it and it works out well.
