1-Getting Started: Mixing the Batter: In a large bowl, whisk together the 4 eggs at room temperature, 1.5 cups milk at room temperature, and 0.75 teaspoon salt until smooth. Gradually add the 1.5 cups flour, spooned and leveled, and whisk until combined. Then, stir in the 2 tablespoons melted butter until the batter is smooth. Let the batter rest while you preheat the oven to 450°F (232°C), which takes about 10 minutes and helps with rising.

2-Preheating and Baking: Generously grease one or two popover pans with butter and place them in the oven for 2 minutes to preheat. This step is crucial for the batter to expand properly. Remove the pans from the oven and pour about 0.25 cup of batter into each well, ensuring there’s room for rising. Bake on a low oven rack for 20 minutes at 450°F (232°C) to get that initial puff.

After 20 minutes, reduce the temperature to 350°F (177°C) and bake for another 10 minutes until the popovers are puffed and golden brown. Once done, pierce the tops with a sharp knife to release steam and serve immediately for the best texture. The total preparation time is about 40 minutes, with 10 minutes for prep and 30 minutes for cooking.
