Separate the yolks from the whites. Whisk the whites with a pinch of salt until they form a stiff foam.
Put the yolks, honey, another pinch of salt, flour, and milk into a separate bowl. Mix well until smooth and then add the carbonated water. Mix again.
Gently fold the egg whites into the egg yolk mixture without breaking the foam.
Heat up 2 inches (5 cm) of oil to 375 F (180 C) to cover the flowers . Dip each flower head into the batter then transfer them immediately into the frying pan.
Fry for 1-2 minutes until golden brown, then drain on a paper towel. Frying can be a little tricky, gently turn the flowers to make sure they cook all the way through.
Serve them fresh, preferably dusted with powdered sugar and cinnamon.
