Red Currant Clafoutis

Clafoutis Batter
0 Preheat the oven to 375 F and place a rack in the center of the oven and another one level below.
2 Melt a tablespoon of butter and pour it into the pan and grease the sides.
3 In a medium bowl, add in the sugar and lemon zest. Rub the zest into the sugar with your fingers. Then add in the eggs, egg yolk, vanilla, and salt and whisk until smooth.

5 Lastly whisk in the heavy cream. Continue whisking until completely smooth.
6 Set the bowl aside while you prep the red currants.
Red Currants
8 Rinse and de stem the red currants directly into the melted butter in the pan. Sprinkle with 2 tablespoons of sugar.
9 Whisk the batter once more and then pout it over the red currants.
Bake
11 Place a baking sheet on the lower rack to catch any overflow.
12 Place the pan with the clafoutis into the oven and bake for 40-45 minutes. It should be brown on the edges and somewhat puffed and jiggly in the center.
13 If you insert the tip of a knife in the center, it should come out clean. If not bake for another 5 minutes.
14 Once baked, remove the pan from the oven and place on a heat safe surface and let it cool for 10-15 minutes.
15 Squeeze the juice of half a lemon over the top and then dust it generously with powdered sugar. Serve immediately. 
16 Leftovers can be kept covered in the fridge once it has cooled off.
