Place sliced onions in a small baking pan (mine was 8 x 11) and pour buttermilk over them.
After all the onions are fully submerged in buttermilk, let them soak at room temperature for 30 minutes - 1 hour.
In a medium sized bowl, mix together flour and salt. Set aside.
In a medium sized sauce pan, pour in about 2 inches worth of vegetable oil.
Heat oil to 350 degrees F.
Working in small batches, dunk some of the soaked onions in the flour mixture, and tap the side of the bowl to get off excess flour. You can use tongs or your fingers.
TIP: Always have baking soda on hand when using oil in case of a flare up
Carefully place small batches of flour coated onions in the oil using tongs (the oil will bubble and rise) and cook until golden brown (this will take a few minutes), use a slotted spoon to break them up.
Once golden, using a slotted spoon, remove the onions from the oil and place on a paper towel lined plate.
Repeat with remaining onions.*
