Pastry Chef Sarah Lewis from The Keeper shares a new take on the traditional key lime pie. Her seafood restaurant is open at the Shops at Legacy across the street from Mexican Sugar.

Cake for 'Key'per

8 each Egg Whites
¾ cup White Granulated Sugar
1 cup Cake Flour
¼ tsp Kosher Salt
1 ½ tsp Baking Powder
4 each Egg Yolks
3 oz Water
3 ½ oz Cottonseed Oil
3 TBSP White Granulated Sugar

Set oven to 325 degrees. Line a 12” x 9” pan with parchment paper and spray with pan spray. Set aside.

Place egg whites in the bowl of a tabletop stand mixer fitted with the whip attachment and whip on speed 4.

In a medium mixing bowl, use a wire whisk to combine ¾ cup sugar, flour, salt, and baking powder. Set aside. In a separate medium mixing bowl, use a wire whisk to combine yolks, water, and oil. Pour oil mixture into dry ingredient bowl and use a wire whisk to fully combine. Set aside.

When egg whites are foamy, turn mixer to speed 10 and let whip for 30 seconds. Once egg whites reach soft peaks, return mixer to speed 4 and slowly stream in 3 TBSP sugar with mixer running. Return mixer to speed 10 and whip for 45 seconds until eggs form medium peaks.

Using a rubber spatula, gently fold ⅓ of the egg whites into the batter. Once fully combined, add remaining egg whites and fold gently.

Pour batter into prepared pan. Spread batter with an offset spatula to make even and lightly tap pan on counter twice to rid batter of bubbles.

Bake in prepared oven for 15 minutes and then rotate pan 180 degrees. Bake for an additional 5 minutes or until cake is golden brown and there is no indent left after lightly touching it.

Upon removal from oven, drop pan onto counter from 6 inches high. Let cool at room temperature. Use a round pastry cutter or paring knife to cut cake circles to fit inside of preferred serving vessel.
