Portuguese Sponge Cake (Pao De Lo)
Ingredients
9 large eggs, room temperature
1 1/2 cups granulated sugar
1 2/3 cups all-purpose flour
1/4 teaspoon baking powder
lemon zest (optional) or
orange zest (optional)
Directions
Preheat the oven to 350°F Grease and
parchment paper line a 10 inch tube pan, set aside.
Beat the eggs with the salt until
light. Gradually beat in the sugar at medium speed and beat for at
least 20 minutes, or until (add rind if using). At low speed, add the
flour mixture to the eggs one heaping tablespoon at a time, blending
well after each addition, and scraping down the sides of the bowl
when necessary.
Pour the batter into the pan and bake
for 40 minutes, or until a cake tester inserted comes out clean (cake
will spring back to a light touch). My cake took a little bit longer. Definitely do the toothpick test.
Let the cake cool in the pan for 10
minutes, then remove from pan and peel off parchment paper. Let cool
completely on rack. Dust with icing sugar before serving if desired.
