Call in someone to soak up the seafood (7)
I believe the answer is:
scallop
'the seafood' is the definition.
(scallop is a kind of seafood)
'call in someone to soak up' is the wordplay.
I cannot quite understand how this works, but
'call in' could be 'call' (synonyms) and 'call' is found within the answer.
'soak' could be 'sop' (dip food in liquid) and 'sop' is found within the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for scallop that I've seen before include "Shellfish - badge worn by pilgrims to Santiago de Compostela" , "Mollusc or lacy edge" , "Bivalve with radiating ridges on shell" , "Seafood - shell" , "Shellfish - pilgrim badge" .)
