I use this recipe:
- 2 eggs
- 9 egg yolks
- Two cups of heavy cream (about 500 ml)
- Salt and pepper
- 500 g spinach or broccoli to fill the bottom of the pan
- Gruyère cheese
First, you bake the pastry till it's crispy. Second you mix the eggs, egg yolk and the cream. Add some spices to it. You can heat it up so it gets baked faster. The spinach should be cooked in hot water for half a minute and then you chop it in little pieces. Add the spinach to the pastry bottom and fill it in with the egg/cream custard.
Then bake it for about an hour on 170 °C. Ten minutes before end you can add some gruyère cheese. Or you can also add the cheese to the custard. It's how you like it. Not too difficult really.
This is the end result:
The taste and texture was pretty good. Not too much liquid, not too dry. Just perfect.
