Cooked steak with ham and eggs, at first, in hurry (4,5)
I believe the answer is:
make haste
'hurry' is the definition.
(I know that hurry can be written as make haste)
'cooked steak with ham and eggs at first' is the wordplay.
'cooked' indicates anagramming the letters (letters cooked into a new form).
'with' is a charade indicator (letters next to each other).
'and' means one lot of letters go next to another.
'at first' says to take the initial letters.
The first letter of 'eggs' is 'e'.
'steak' after 'ham' is 'hamsteak'.
'hamsteak' anagrammed gives 'makehast'.
'makehast'+'e'='MAKE HASTE'
'in' is the link.
(Other definitions for make haste that I've seen before include "Hurry, don't be slow" , "speed" , "Shake mate to hurry up" , "Festina lente - . . . . . . . . . slowly" .)
