Times Cryptic Jumbo 1595 – 14 January 2023. Macing the kut

Hi all.  No time to report as I solved over several sessions, but I was certainly not fast.  I had also, in 15a, plumped for a K where the solution demanded a C.  Not being familiar with the word I simply assumed that I had made a wrong guess, but later discovered that my answer is a valid spelling.  I won’t get my knikcers in a twist over it though. I enjoyed it all very much while solving. Thanks setter!
