I squeeze into new suit for dessert (8)

I believe the answer is:

tiramisu

I'm a little stuck... Click here to teach me more about this clue!

'for dessert' is the definition.
(I've seen this before)

'i squeeze into new suit' is the wordplay.
'i squeeze' becomes 'rami' (I am not sure about this - if you are sure you should believe this answer much more).
'into' is an insertion indicator.
'new' is an anagram indicator.
'suit' with letters rearranged gives 'tisu'.
'rami' put within 'tisu' is 'TIRAMISU'.

Can you help me to learn more?

(Other definitions for tiramisu that I've seen before include "Arenaceous material" , "Italian course" , "Rich Italian dessert" , "Dessert soaked in alcohol" , "Dessert (Italian "pick me up")" .)
