Thanks for these, Jolan. Hope you and yours are in good health. Returned from the wild to this treat. Great clues.
Here is my stab at them.
1. Regularly enters shallow vessel in front of river gambling establishment, possibly (10,5)- DISORDERLY HOUSE? (Dish – shallow vessel, with “orderly” – regularly inside , with the river Ouse gives Dis orderly h Ouse- a gambling establishment possibly?)
2. Poisonous growth rises to the top in various orders? (9) MONKSHOOD? (A monk’s hood would “rise to the top” in various monastic orders and monkshood is a poisonous growth?)
3. Medically looking into excruciatingly badly cut cuticle (1-6)- X-RAYING? (Signature subtractive anagram. “Excruciatingly” with “cuticle” removed and “badly” as anagrind gives x-raying- medically looking into?)
4. Ends the issue of a legitimate RM in Ireland (7) TERMINI? (Ends – letters are in clue)
5. Smelly jelly? (4,9) HIGH EXPLOSIVE? (Smelly – high, jelly –gelignite etc )
Thanks again.
