Eggs for two people, ultimately? (3)
I believe the answer is:
roe
'eggs' is the definition.
(fish eggs)
'for two people ultimately' is the wordplay.
'ultimately' suggests the final letters.
The final letters of 'for two people' are 'ROE'.
(Other definitions for roe that I've seen before include "Hoofed animal(s)" , "Mass of fish's eggs" , "Lobster's ripe ovary" , "shy animal" , "Food from fish" .)
