Prepare the Onion
Cut off the top of the onion, leave the root intact.

In another bowl, whisk milk and egg.
Coat the Onion
Dip onion into the flour mixture, getting between petals.
Dip into milk-egg mixture, then back into flour mixture for extra crunch.

Carefully lower onion into oil, cut-side down first.
Fry 8–10 minutes, turning once, until golden brown.
