Dip and fry the blossoms. Working in batches of 5 to 6, dip each blossom into the batter one at a time. Add to the oil and fry, flipping once, until golden-brown, about 2 minutes per side. Use a slotted spoon to transfer the fried blossoms to a paper towel-lined plate to drain. Repeat dipping and frying the remaining blossoms, making sure the oil is at 375ºF for each batch.
