Spring onions found their way into several of this week’s quiches. For this one, I cooked the onions with cabbage – even a half a head of cabbage that has been lingering in your refrigerator will work here – until both vegetables were soft, lightly colored and sweet. I added caraway seeds to the mix because I love the flavor of caraway with cabbage. I used 1/2 teaspoon, just enough so that people noticed; they couldn’t recognize what it was (“Cumin?” they asked) right away, but they liked it. I made the filling a day ahead and let it sit uncovered overnight in the refrigerator.
03Beat 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.)
04Add salt (I use 1/2 teaspoon), pepper, and milk to remaining eggs and whisk together.
05Spread 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.
