Equipment
Method
- Heat oven to 350 degrees with a rack in the center.
- In a large bowl, combine butter, sugar, lemon zest and salt, using a wooden spoon to mash together. Mix in egg yolks, then mix in flour. Whisk in lemon juice and milk.
- In a small bowl, stir blueberry jam to loosen.
- Using a whisk, electric mixer or electric beaters, beat egg whites to stiff peaks. Fold into batter.
- Pour batter into a glass pie dish or shallow gratin dish and use a spoon to top with small dollops of jam. Bake until golden brown on top and just set (a wiggle in the center is fine), about 30 to 35 minutes. Cool for 10 minutes, then use a spoon to serve warm or room temperature with a dusting of powdered sugar.
Notes
I used Diamond Crystal fine kosher baking salt.
