GRATED (seems like the clue should be referring to the food rather than its property), HONOUR (assumes British rather than American English; I don't know which Alenanno prefers), BREADS (the S is from "sunrise" and seems rather unsatisfactory), DETACH (surely there should be something better). Of these, I think I have good evidence for GRATED, HONOUR and DETACH but BREADS remains dubious.
ERUPTS has been mentioned as possible for "lose one's temper", but it seems wrong in something like the same way as GRATED. (I make another proposal for it below.)
die 13 which (unless one of the unsolved clues provides something helpful) seems to have to have a residual of TLD, and be both preceded and succeeded by quite consonant-heavy stuff. The best I can find at present is .../WOR/LD T/... but if so then I think we need something else for die 14. And, aha!, we can join these two blocks together to get CHTHONIC GOD OF THE UNDERWORLD which sounds awfully promising. That would mean that die 11 has a residual of DER so that word is an anagram of ADDENR; perhaps DANDER is the intended answer to the clue about losing one's temper, though I don't think it actually quite works if so. And, aha! again, it surely must be ANCIENT GREEK CHTHONIC GOD OF THE UNDERWORLD (hence my confidence that the final answer is HADES) which means I'm missing a word with an I in it for die 2. Perhaps our leafy-vegetable one is TISANE.
At this point we have just the last part of the final definition to figure out ... and I'm having real trouble finding anything that fits with anything else. I suspect BREADS is wrong; it might be DANISH (going on die 18 or 19) but while that's a more satisfactory answer to the clue it doesn't make it any easier to piece the residuals together.
