Method
In a blender or large mixing bowl, combine the room temperature whole milk, eggs, and 30g melted unsalted butter. Blend or whisk aggressively until completely homogenous.
Add the all-purpose flour, buckwheat flour, and kosher salt to the liquid mixture. Blend or whisk just until smooth, ensuring there are no dry pockets of flour. Avoid overmixing.
Cover the batter and let it rest at room temperature for at least 1 hour. This resting period hydrates the starches and relaxes any developed gluten, which is essential for a good rise.
Place the empty mini popover pan or muffin tin in the oven and preheat the oven to 230°C (450°F). Allow the pan to heat for at least 10 minutes.
Carefully remove the hot pan from the oven. Working quickly, brush the cavities with the remaining 15g of melted unsalted butter to coat the bottoms and sides.
Immediately pour or ladle the rested batter into the hot pan cavities, filling each about half to two-thirds full.
Return the pan to the oven and bake at 230°C (450°F) for 12 minutes. Absolutely do not open the oven door during this stage, or the popovers will collapse.
Reduce the oven temperature to 175°C (350°F) and continue baking for another 10 to 13 minutes until deeply golden and crisp.
Remove the popovers from the oven. Using a small paring knife, immediately pierce a small slit in the side of each one to let trapped steam escape, preventing sogginess.
Transfer the popovers from the pan to a wire cooling rack. Let them cool slightly; they should be just warm to the touch before adding the chilled toppings.
Pipe or spoon a small dollop of crème fraîche onto the top or into the pierced slit of each popover. Top each with a generous quarter-teaspoon of caviar and a sprinkle of finely minced fresh chives. Serve immediately.
Chef's Notes
- For the highest rise, ensure your milk and eggs are fully at room temperature or even slightly warm. Cold batter placed in a hot oven will not create the aggressive burst of steam needed for an airy popover.
- Resting the batter is non-negotiable. It thoroughly hydrates the starches in both the all-purpose and buckwheat flours, leading to a more elastic structure that can trap steam efficiently.
- Buckwheat flour lacks gluten development. Combining it evenly with high-protein all-purpose flour provides the necessary structural integrity while fully maintaining the rustic, nutty flavor profile.
- Keep your crème fraîche and caviar as cold as possible right up until assembly. The contrast between the warm, crisp popover and the chilled, rich toppings is what makes this dish exceptional.
Storage
Refrigerator: 1 day — Unfilled popovers only.
Reheating: Reheat unfilled popovers in a 175°C (350°F) oven for 3-5 minutes until crisp before topping.
