My understanding is popovers are individual servings of Yorkshire pudding.
For Christmas Eve we are having beef tenderloin roast (delicious, elegant, and quick to prepare after work, as opposed to a bigger roast). I am seasoning by pulverizing dried mushrooms in food processor and coating meat with it. Sooooo good! Sides will be roasted veggies, hopefully asparagus, butI it depends on what I find at the store, and potatoes. Dessert will be cookies that are already made and in freezer. Apps will be whatever I decide is easy to make.
