I grew up in St. Louis. Everyone has one favorite item at each restaurant. My favorite at KC Masterpiece was the giant mound of crispy sweet onions on top of every meal. I think I perfected a perfect replica and I am really excited about them.
1 yellow onion thinly sliced
2-3 cups of whole milk
1/4 cup lemon juice or lime juice
2 cups all purpose flour
salt and pepper or seasoning to taste (I use a lot of cajun seasoning)
Thinly slice the onion. The thinner the better. Place the slices in a bowl. Cover them with milk and the lemon or lime juice. Let this sit for 30-45 minutes.
Heat the oil in a deep fryer to 375 degrees. Season the flour using salt and pepper. Dredge the onions. Make sure to coat them until they are fully dry to the touch with flour. Fry for about 3-4 minutes or until golden brown.
