2tablespoonssalted butter28 grams (melted, for greasing pan)
6 to 12teaspoonsraspberry jam30 to 60 grams (1 to 2 teaspoons per cup)
Instructions
Preheat the pan – Place the empty popover pan or muffin tin in the oven and preheat to 450°F. Let it heat for the full preheat time.
Mix dry ingredients – In a medium bowl, whisk together the flour and salt.
Combine wet ingredients – In a large bowl, whisk together the warm milk, room temperature eggs, and sourdough starter or discard until smooth and slightly frothy.
Make the batter – Add the flour mixture and vanilla extract to the wet ingredients. Whisk until just combined. Do not overmix.
Butter the hot pan – Carefully remove the hot pan from the oven. Brush each cup generously with melted butter. It will sizzle immediately.
Fill and add jam – Fill each cup three-quarters full with batter. Drop 1 to 2 teaspoons of raspberry jam on top of the batter in each cup.
Bake at high heat – Return the pan to the oven and bake at 450°F for 15 minutes without opening the door.
Reduce and finish – Reduce to 375°F without opening the door. Bake for another 10 to 15 minutes until deep golden and puffed.
Serve – Transfer to a wire rack and serve within 5 minutes with butter or extra raspberry jam.
Notes
Hot pan is essential – The pan must be screaming hot before any batter touches it. This is what drives the dramatic rise.Room temperature ingredients only – Cold eggs or cold milk slow the steam burst and produce a flatter result. Pull them from the refrigerator at least 30 minutes before baking.Do not open the oven door – Not during the first 15 minutes under any circumstances.Make ahead batter – Batter keeps covered in the refrigerator for up to 24 hours. Bring to room temperature before using.
