Heat the oil in a heavy-bottomed 10-inch skillet (cast iron works well) over medium-high heat.
Stir together the flour, arrowroot, baking powder, salt, paprika, and pepper.
Add the egg and sparkling water to the flour, and stir to combine. It may be a bit lumpy, but that’s ok.
Drip a tiny bit of the batter into the oil to test for heat. It should sizzle immediately; if it doesn’t, let it heat for a few more minutes.
Once the oil is hot, use tongs or chopsticks to dip the dandelion flowers into the batter, coating them evenly. Then, carefully place the dandelions into the hot oil. The flowers will immediately sizzle. Depending on the size of your skillet, you may need to work in batches.
Fry each flower for 30-60 seconds, then flip and cook another 30-60 seconds until they are light golden brown all over. Use tongs or chopsticks to carefully remove each flower from the hot oil and transfer it to a plate lined with a paper towel.
Notes
Forage dandelion flowers from a place that isn’t sprayed with chemicals and is free of pet waste.It’s okay to harvest the dandelions with the stem on, so they’re easier to dip in the batter and oil, but just eat the blossoms. And don’t forget to save any greens for other uses!
