Tear-jerker set in kitchen? (5)
I believe the answer is:
onion
'tear-jerker' is the definition.
(cutting onions can make you cry)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for onion that I've seen before include "Plant with edible bulb" , "Eye-watering vegetable" , "Shape of Russian dome" , "Tear-jerking bulb" , "Bulb used in cooking" .)
