Preheat oven to 325 Fahrenheit.
In a large bowl, whisk together the milk, orange zest, eggs, sugar, vanilla and melted butter until everything is well combined.
Then add the flour, cinnamon and salt and whisk together well. It should look like pancake batter.
Pour the batter into a medium oven safe dish or cast iron and scatter fruit all over the top. Some will sink and some will stay at the top.
Bake for 35-38 minutes until the clafoutis is puffed and lightly golden brown.
