Bottom of egg fried badly in kitchen appliance (6)
I believe the answer is:
fridge
'kitchen appliance' is the definition.
(fridge is a kind of kitchen appliance)
'bottom of egg fried badly' is the wordplay.
'bottom of' indicates one should take the final letters.
'badly' indicates anagramming the letters.
The last letter of 'egg' is 'g'.
'g'+'fried'='gfried'
'gfried' anagrammed gives 'FRIDGE'.
'in' is the link.
(Other definitions for fridge that I've seen before include "Cooler in kitchen" , "A domestic appliance" , "Cooling cabinet (abbr)" , "Food cooler" .)
