Spoon, in a big way, with Della (5)
I believe the answer is:
ladle
'spoon' is the definition.
(I know that ladle is a type of spoon)
'a big way with della' is the wordplay.
'della' anagrams to 'LADLE'.
Though, I am not sure how the anagram is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for ladle that I've seen before include "Perhaps stock holder" , "It's used to serve soup" , "one in 10 [GRUEL] ?" , "Serving implement" , "Soup-server" .)
