8 small purple or green kohlrabi bulbs (about 2 in. diameter), leaves and stems trimmed
1 teaspoon yellow mustard seeds
1 teaspoon brown mustard seeds
2 bay leaves, preferably fresh
2 tablespoons sherry vinegar
4 teaspoons honey
1 tablespoon stone-ground mustard
1 ounce chopped stemmed fresh sorrel* (about 1/2 cup), plus several small leaves for garnish
4-in. piece honeycomb* or 2 tbsp. honey
How to Make It
Preheat oven to 250°. Put unpeeled eggs in a bowl of warm water. Pour 1/4 cup oil into an 8- by 8-in. pan, add kohlrabi, and turn to coat. Cover tightly with foil.
Remove eggs from water and set directly on an oven rack. Set pan of kohlrabi on another rack. Roast eggs and kohlrabi 2 hours (eggs will be freckled with brown syrupy spots). Remove eggs, crack all over under cold running water, and put in a bowl of cold water to cool.
Turn kohlrabi over in pan and cover tightly. Increase oven temperature to 375° and roast kohlrabi until butter-soft when pierced with a knife, about 1 hour. Remove foil, turn kohlrabi over, and roast until crisply browned, about 30 minutes more.
Meanwhile, in a small saucepan, heat mustard seeds over medium-high heat until just starting to pop, 2 to 3 minutes. Add 1/2 cup water, the bay leaves, vinegar, and honey. Bring to a boil, then lower heat and simmer, covered, until mustard seeds are tender, 15 to 20 minutes. Uncover and boil sauce until reduced to 1/2 cup, 2 to 5 minutes. Remove from heat and whisk in mustard. Season with salt to taste.
Peel eggs. Chop and mix with sorrel in a medium bowl.
While kohlrabi bulbs are still warm, tear some partway apart and some in half.
Spoon egg-and-sorrel mixture among 4 plates or on a big platter. Arrange kohlrabi over the mixture, drizzle with honey-and-mustard sauce, and add a few small chunks of honeycomb. Top with small sorrel leaves.
*Jeremy Fox uses red sorrel, wood sorrel, and sheep sorrel from Ubuntu's garden, but any kind of sorrel will work. Find honeycomb at well-stocked grocery stores and farmers' markets.
Quick twist: Replace the kohlrabi with small unpeeled Yukon Gold potatoes. Roast and serve them exactly the same way.
This was just ok for an afternoon's work and after sourcing some out-of-the-way ingredients (i.e., sorrel, which Whole Foods didn't even have; used mache instead...and brown mustard seeds which were a bit $$). Two hours is too long to roast eggs; while they didn't explode as I had feared, they turned out brown and shriveled with green rings around the yolks. I had thrown in two more after deciding to add potatoes to make up for my limited kohlrabi, and the second two were much better after having roasted for an hour and then coasting. My kohlrabis were unfortunately on the tough and woody side and so never reached the "butter-soft" stage, but the dish turned out edible, if a bit meager. I might make this again, simply hard-cooking the eggs in water and serving some bread or a light soup alongside.
