@@RedFoxworthy-p1qGordon Ramsey is well known in the US thanks to his appearances, but is seen as something of a joke in the UK compared to Delia, Nigella, Rick Stein, even Jamie Oliver. I would rank Ainsley up there as someone who is known by his first name alone - comparable to Delia and Nigella for example.
No idea who White is (Marco Pierre White maybe?) and Julia Child is seen as an America cook primarily, not particularly well known to UK audiences.
