Onion jam, which is reason enough to try this sandwich, is simple to make (see the recipe for Blaak Onion Jam at beekman1802.com, which also sells the jam by the jar). Although any blue cheese is delicious here, look for one that's sliceable or crumbly, not gooey. Stilton, Maytag, and Roaring Forties are good choices.
This versatile dish goes from brunch buffet to dinner table in a snap and is great with a leafy green salad. The flaky crust and custard filling make it a perfect vehicle for an array of mix-ins.
Baking the crust before adding the filling, known as blind baking, ensures it won't get soggy. Our favorite pie dough recipe is Basic Pie Crust.
Carve an eye-catching serving bowl for this dip (and any others): Cut about a 4-inch-diameter round out of the top of a head of cabbage using a paring knife, then scrape out the center using a large metal spoon.
