Lovely easy grid to solve, clear groups, no swappable answers, well constructed. 'The elements named after planets' link was rather odd though, as it's literally just a list of planets, and needs nothing else in the description to avoid swaps with other groups, but apparently 'elements' is needed for the point.

Fun!!

They aren’t the elements - they are the planets - at best it would be planets after which elements are named - and the status of Pluto throws a spanner in those works too!

Agree that the planets one is overly complicated, but the element aspect does avoid a possible swapover with uranus going in what would then become simply body parts.

Ace...that's the definition of a red herring. Nice grid but elements named after planets they are not.

I used “confectionary” for the sweets/chocolate group but apparently it’s “names of confectionary” which is a bit annoying!
