Crazy eg ceding best dish (4,8)
I believe the answer is:
eggs benedict
'dish' is the definition.
(eggs Benedict is a kind of dish)
'crazy eg ceding best' is the wordplay.
'crazy' indicates an anagram.
'eg'+'ceding'+'best'='egcedingbest'
'egcedingbest' anagrammed gives 'EGGS BENEDICT'.
(Other definitions for eggs benedict that I've seen before include "something for breakfast?" , "Dish served on toast" , "Dish with ham on toast" , "snack" , "Dish topped with hollandaise sauce" .)
