Great recipe but I want to offer a little suggestion and ask for advice from others who had made this. I made this as written twice but thought the crust was too dark(an unappealing almost burned brown color) at 350 degrees using my Bravetti Platinum Pro deep fryer. So on the third try I changed it to 325 degrees...MUCH better.(same frying time 10 minutes for a very large vidalia onion) Now for the other challenge the recipe did not state how long to par-boil the onion. The first try I did six minutes but flower collapsed. The second try I cut the time in half to 3 minutes but the onion was almost raw and the petals did not coat properly except on the outside. The third try I did 5 minutes which I think is about right EXCEPT the flower collapsed again after coating due to the weight. (everything tasted wonderful but was visually unaesthetic). I THINK the problem might be resolved by NOT cutting the core all the way through to the other side and instead leave the base intact 1/2"- 3/4". Anyone here have a similar experience and would like to share their strategy? One other alteration I made on the third try was reducing the amount of buttermilk from 1 cup to 3/4 cup. It may have been the brand I was using but on the first two attempts I thought the batter was too thin. After I reduced it to 3/4 cup I thought the coating clung much better. Thanks Rita for sharing your recipe.
