Fantastic Onion Ring Batter

I just heard on TV that it is National Onion Ring Day!! So, I immediately googled recipes, and this is the one I picked.
(no serving size given)

2 large sweet* onions, cut into pretty thick* rings, or to your liking*
1 cup all-purpose flour, plus 2 T.
1 cup whole* milk
1 egg
2 T. veg. oil, plus more for frying
1 t. kosher* salt

Soak onion rings in a bowl of ice water for 1 hour; drain and pat dry with paper towels. Whisk 1 cup plus 2 T. flour, milk, egg, 2 T. veg. oil, and salt together in a bowl until smooth. Heat oil in a deep-fryer or large saucepan to 375. Dip onion rings in the batter, working in batches, until evenly coasted and arrange in 1 layer on a plate. Fry the battered rings, working in batches, until browned, about 5 mins. Transfer when done to a paper towel lined plate using a slotted spoon. Salt, to taste.

"For a seed to achieve its greatest expression, it must come completely undone. The shell cracks, its insides come out, and everything changes. To someone who doesn't understand growth, it would look like complete destruction."
