This quick dinner side dish made with matzo has a humble look but a rich flavor, thanks to duck fat. Serve with roast meats.
Preheat oven to 375 degrees. Melt fat in a medium skillet over medium-high heat. Add onion and celery; cook 8 minutes. Let cool. Whisk together eggs, broth, 1 1/4 cups hot water, spices, and salt. Stir in farfel and onion mixture. Spoon into 10 (1/2-cup) ramekins. Bake until set, 30 to 35 minutes.
