- Whisk the eggs and granulated sugar together
in a medium bowl until thick. Add the vanilla 
and salt. Whisk in the flour; don’t worry if you
 see little bits of it in the batter. Beat in half the 
milk until combined, then the rest. Refrigerate
 the batter until you’re ready to use it. 
- Coat the inside of a 10-inch cast-iron skillet
 with the butter. Pour the cherries into the pan
 in a single layer. Leave at room temperature 
until you are ready to bake the clafoutis. 
- If using a gas grill, heat it for medium-high
 direct cooking. The grill temperature should be 
500° to 600°F; it could mean all the burners 
are on medium or medium-low depending 
on your particular grill. If using a charcoal
 grill, after taking dinner off, add more coals if
 necessary and close the lid until you’re ready 
to bake. 
- Pour the batter over the cherries and give the 
pan a little shake to even everything out. Put 
the pan on the grill directly over the fire. Close 
the lid and bake for 7 minutes, then check 
on its progress. If the pudding seems to be 
browning too fast, turn the heat off under the 
pan and turn it up on the other burners for a 
gas grill, or move the pan to a cooler part of 
the charcoal grill. Continue to bake, checking 
every few minutes, until the edge puffs up
 and pulls away from the pan and the center is
 set, 3 to 12 minutes more, depending on how 
hot the fire is. Carefully transfer the pan to a 
rack and let cool for a few minutes. Sift a little
 confectioners’ sugar over the top, then cut into
 wedges or spoon out of the pan and serve.
