I was at a French restaurant with my family and ordered a traditional onion soup, with the cheese forming a seal over the top of the bowl.Knowing the exact level of both my credulousness and my pretentiousness, my brother told me that the traditional French way to ‘break the seal’ was to use one’s thumb.
It was only my mum’s shouting ‘Rob NO’ that prevented me from plunging my thumb through a layer of molten cheese, into a vat of piping hot soup.
