This recipe makes quite a bit of batter, possibly more than you'll use for 10 or so sage leaves per person. If you have leftover batter, you can cover and keep it in the refrigerator for a couple of days and use it to make other vegetable tempura.
A note on olive oil: for frying, we recommend using pure olive oil. Extra virgin olive oil may be used, but it is more expensive and has a lower smoke point.

Large fresh sage leaves (about 10 per person)
1 cup ice water
1 cup all-purpose flour
Fleur de sel or other coarse sea salt
Remove sage leaves from stems and wash and pat dry.
Sift flour into a medium bowl. In a separate small bowl, beat egg and mix in water. Gradually stir egg mixture into flour. The consistency should be lumpy. Chill batter in refrigerator until ready to use.
Heat about 1 inch of oil in a deep pan.
Dip sage leaves into the batter. The leaves should be lightly coated; shake or squeeze off any excess batter.
Fry until golden, remove from oil, and drain on a towel. Serve immediately with a sprinkle of lemon juice and salt.
