During testing, our staff proclaimed that these were the most delicious Brussels sprouts they’d ever had. To save time, you can easily substitute frozen Brussels sprouts and pearl onions.
Peel, quarter, and blanch the Brussels sprouts in boiling salted water. Plunge into an ice water bath to stop cooking. Drain and set aside.
In a medium frying pan over moderate heat, saute onions in the vegetable oil until they caramelize nicely, about 8 to 10 minutes. Add shallots, ginger, and thyme. Season with salt and pepper and saute 3 to 4 minutes longer.
Add the brandy (or equivalent) to the pan, let warm briefly, then remove pan from the burner. Working very carefully, light the liquor with a long match and allow the liquid to reduce. As a safety measure, keep a lid nearby to douse the flames if needed; the liquor will flame about 15 to 30 seconds before going out on its own. Add cream, honey, and vinegar, then simmer until the sauce thickens about 4 minutes. Add the brussels sprouts and stir. Season with salt and pepper to taste. Garnish with fresh herbs, if desired.
