Thanks for the welcome back guys :-)
I am indeed a refugee of the Les Jone forum, won't go into details and rake up bad blood, but in the end I had had enough and was glad to be expelled :-)
Good to see your video Chewy using the whole onion technique. I have tried to look into the science behind it and there is something around a chemical reaction happening once you slice into an onion, so assume this technique relates to not starting that chemical reaction off prior to cooking the onions?
Anyway, although not a game changer in terms of base gravies, it is something I will continue to use, even with the risk of the odd bad onion!
