Quiche with Cabbage and Spring Onion

Heat olive oil over medium heat in a large, heavy skillet and add onions. Cook, stirring often, until tender, about 5 minutes. Add a generous pinch of salt and continue to cook 3 to 5 minutes, until beginning to color. Add cabbage and cook, stirring often, until cabbage wilts, about 5 minutes. Add another pinch of salt and caraway seeds and continue to cook for another 5 to 10 minutes, until cabbage is sweet, cooked down, lightly colored and very tender. Taste, adjust salt, and add freshly ground pepper. Remove from heat.

Beat together egg yolks and eggs in a medium bowl. Set tart pan on a baking sheet to allow for easy handling. Using a pastry brush, lightly brush the bottom of the crust with some of the beaten egg and place in the oven for 5 minutes. (The egg seals the crust so that it won’t become soggy when it comes into contact with the custard.)

Add salt, pepper, and milk to remaining eggs and whisk together.

Spread cabbage and onion in an even layer in the crust. Sprinkle cheese evenly on top. Very slowly pour in the egg custard over the filling. If your tart pan has low edges, you may not need all of it to fill the quiche, and you want to keep the custard from spilling over. Place quiche, on baking sheet, in oven and bake for 30 to 35 minutes, until set and just beginning to color on top. Remove from oven and allow to sit for at least 10 minutes before serving.
