UPDATE: Gabrielle Drake! It has been puzzling me for ages but thanks to a reply below, I now know who she is. Here's a link to her IMDB page: https://www.imdb.com/name/nm0236907/?ref_=ext_shr
There is an advert on UK TV at present (Dec 2025), where a son makes a tarte tatin for his mum using instructions on Tiktok. (Wasn't sure how to add the image to my post, so it's in the comments)
The actress looks very familiar – maybe from a programme years ago. I've tried Google Lens and it comes up with nothing and a general search is swallowed up by Tiktok related answers. I've searched on here as well to no avail.
I'm sure she was in something very popular, but can't place her. Does anyone know who she is?
Many thanks in advance and happy new year to you all.
