Where all that ice can be broken with ease (5,3)
I believe the answer is:
white sea
'where all that ice can' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'broken with ease' is the wordplay.
'broken' is an anagram indicator.
'with'+'ease'='withease'
'withease' anagrammed gives 'WHITE SEA'.
'be' acts as a link.
Can you help me to learn more?
(Other definitions for white sea that I've seen before include "A quantity of salt water" , "Russian waters" , "Inlet of the Arctic" .)
