One realizes that human relationships are the tragic necessity of human life — that they can never be wholly satisfactory, that every ego is half the time greedily seeking them, and half the time pulling away from them. In those simple relationships of loving husband and wife, affectionate sisters...there are innumerable shades of sweetness and anguish which make up the pattern of our lives.What a wonderful passage; it is also the epigraph to Nancy Milford's biography of Edna St. Vincent Millay, Savage Beauty.
--Not Under 40, Willa Cather
The cake calls for 7 eggs and tastes very similar to a steamed Cantonese sponge cake (馬拉糕) served at some dim sum places. If you're a fan of egg-flavored desserts (custard buns, egg tarts, etc.), you'll adore this cake.
adapted from America's Test Kitchen
1 1/2 cups sugar
1 1/3 cups flour
2 tsp baking powder
1/2 tsp salt
5 egg whites
5 egg yolks + 2 whole eggs
3/4 cup water
1/2 cup oil
1 tbsp vanilla extract
1/2 tsp almond extract
Preheat oven to 325°F. Adjust oven rack to lower-middle position and grease a tube pan (preferably one with a removable bottom).
Whisk the sugar, flour, baking powder, and salt together in a large bowl. In a medium bowl, whisk the 5 egg yolks, 2 eggs, water, oil, and extracts together. Slowly whisk the yolk mixture into the flour mixture until smooth.
In a large bowl with high sides, beat the 5 separated egg whites with an electric mixer on medium-low speed (I used #2 setting) until foamy, about one minute. Increase speed to medium-high (#4 setting) and whip to stiff peaks, another 3–4 minutes. "Stiff peaks" mean that when you lift the beaters from the egg whites, the peaks stand up straight, without curling at all. Fun fact: By the time it reaches this point, you could hold the bowl upside down over your head and the egg whites still wouldn't budge.
Gently fold the whipped egg whites into the batter with a rubber spatula until combined. Transfer the batter to the prepared pan and tap the pan gently on the counter a few times to settle the batter. Bake 50–60 minutes (mine only took 45 minutes, though), until the cake is golden brown and the top springs back when pressed firmly.
Note: If you want to prevent the finished cake from deflating as much as possible, invert the tube pan over the neck of a sturdy bottle (such as a champagne bottle), or devise some other method of letting it cool upside down.
