As you are all so good and my brain isn't working here's some more:- 13. Coloured desert (5,7) 14. Hiker's stick without stock (5) 15. Drive a dogsled past part of a house (8) 16. Overdramatic emotion gets confused with changing a vowel (9) 18. Prattle on (6) 19. Restart without part of one (5) 20. Quiet colour passes on (9)
ont-ice - sorry have just logged on again, but to answer your question the clue no 13 is written as coloured desert, but it could easily be a typing error as i do think black pudding is the answer
