Lemon-Almond Butter Cake

Step 1

For the curd, combine zest, juice, sugar and eggs in a heatproof bowl, and beat well. Add butter, and place over a saucepan full of simmering water. Cook, stirring constantly with a rubber spatula or wooden spoon, until mixture thickens into curd, about 5 minutes. Strain into a bowl, and press plastic wrap onto surface to keep skin from forming. Refrigerate until cool, at least 1 1/2 hours.

Step 2

Heat oven to 350 degrees. Grease 9-inch spring-form pan with 1 tablespoon butter, and dust with 1 tablespoon flour, shaking out excess.

Step 3

With an electric mixer, cream the remaining butter and 1 cup sugar together until light and fluffy. Sift together the remaining flour, baking powder and salt, and stir in. In a separate bowl, whisk eggs until they start to foam. Do not overbeat or the cake will be tough. Add eggs and ground almonds to batter, and mix well.

Step 4

Scrape batter into the prepared pan. Drop 8 individual tablespoons lemon curd around perimeter of batter, leaving a 1-inch border, and taking care to space drops evenly. Drop 3 to 4 tablespoons curd into center of batter. Refrigerate remaining curd for another use. Sprinkle cake with toasted almonds and 1 to 2 tablespoons sugar, depending on taste.

Step 5

Bake until cake is toasty brown on top and a toothpick inserted into cake (not curd) comes out clean, about 40 minutes. Let cool on rack 10 minutes, then remove sides of pan, and cool completely.

Step 6

Whip cream with almond liqueur. Present cake at table, and offer whipped cream on the side.
