Test kitchen tip

Buttermilk can be frozen. To freeze, measure one-cup portions in freezer containers. Thaw in the fridge and be sure to shake before using.


Preheat oven to 325°.

Coat an 8½×4½-inch loaf pan with butter; sprinkle with coarse sugar.

Whisk together flour, ½ tsp. salt, baking powder, and baking soda.

Whisk together buttermilk and 1 Tbsp. lemon juice in a measuring cup with a pour spout.

Whip egg whites in a bowl with a hand mixer on medium-high until foamy; slowly add 2 Tbsp. granulated sugar while continuing to whip whites until they're thick, glossy, and form soft peaks.

Cream 1 stick butter, 1 cup granulated sugar, and zest in a stand mixer fitted with the paddle attachment on medium speed until light and fluffy, 35 minutes.

Beat in egg yolks, one at a time, until combined. Add flour mixture in three additions and buttermilk mixture in two additions, alternately, starting and ending with flour mixture.

Fold 6 oz. blueberries into batter then fold in one-third egg whites until combined. Gently fold in remaining whites just until combined. Transfer batter to prepared pan; smooth top.

Bake cake until golden brown and a toothpick inserted into center comes out with just a few crumbs, 6575 minutes. Let cake cool in pan on rack 10 minutes, then turn out onto rack to cool completely.

Meanwhile, purée remaining 6 oz. blueberries, water, remaining 3 Tbsp. granulated sugar and 2 tsp. lemon juice, and pinch of salt in a blender; strain coulis through a fine-mesh sieve and chill until ready to use.

Dust cake with powdered sugar; serve with coulis.
