Orange Sponge Cake

August 8th. I am thirty-nine. Miya is eight. Miya's Kitchen at the community kitchen: twelve children in aprons, three stations, two hours of beautiful chaos. The miso soup station was the revelation — twelve children making dashi, dissolving miso, tasting the result, and the tasting-faces were the review: surprise, then analysis, then approval. The same three expressions that Miya made when she first tasted dashi at seven. The expressions are universal. The dashi is universal. The surprise-analysis-approval is the human response to discovering something that has been there all along, waiting to be noticed.

Brian came to the party (on time, the new Brian, the post-parking-lot Brian who checks the shared calendar and arrives when the calendar says arrive). He brought a present for me (a gift certificate to Uwajimaya, which was either Brian having a moment of insight or Lisa suggesting it, and either way: perfect). He stayed for the whole party and helped with cleanup and the helping was the change and the change was the progress and the progress was the turning point, still turning, still in motion.

I turned thirty-nine and wrote a blog post about the last year of the thirties — about how the thirties were the decade of destruction and reconstruction, the decade of marriage and motherhood and divorce and grief and the chipped bowl and the first book and the beginning of the career. The thirties were the fire. The forties will be — I don't know what the forties will be. I don't need to know. I need to make miso soup tomorrow morning. The tomorrow is enough. The not-knowing is the faith. The faith is the practice.

Miya made me a card: "Happy Birthday Mama. 39 is almost 40 and 40 is almost old and old is almost wise and wise is almost you." The almost-chain was mathematical and poetic and entirely Miya: building a logical argument that ends in a compliment. Almost wise. Almost me. The almost is the space. The space is the practice. The practice is almost wisdom. Almost is close enough.

Miya’s card said almost-wise, and I decided almost-wise people make their own birthday cake — something bright and light that tastes like you meant it. After two hours of beautiful chaos at the community kitchen and a gift certificate to Uwajimaya burning a happy hole in my pocket, I wanted something that felt like a real occasion without pretending the occasion was anything other than exactly what it was: thirty-nine, present, grateful. Orange sponge cake is the right answer to that question. It rises on air and citrus and a little faith that the oven will do what ovens do, which is the whole point.

Prep Time: 20 min | Cook Time: 35 min | Total Time: 55 min | Servings: 10

Ingredients

6 large eggs, separated, at room temperature
1 cup granulated sugar, divided
1/3 cup fresh orange juice (about 2 medium oranges)
1 tablespoon orange zest
1 teaspoon vanilla extract
1 cup all-purpose flour, sifted
1/4 teaspoon salt
1/2 teaspoon cream of tartar
Powdered sugar, for dusting (optional)
Whipped cream and fresh orange slices, to serve (optional)

Instructions

Preheat and prepare. Preheat oven to 325°F (165°C). Do not grease your tube or angel food cake pan — the batter needs to cling to the sides to rise properly.
Beat the yolks. In a large bowl, beat egg yolks with 3/4 cup of the sugar on high speed until the mixture is thick, pale, and falls in ribbons, about 4–5 minutes. Beat in the orange juice, orange zest, and vanilla extract until combined.
Fold in the flour. Gently fold the sifted flour and salt into the yolk mixture in three additions, using a spatula. Stir only until no dry streaks remain — do not overmix.
Whip the whites. In a clean bowl, beat egg whites with cream of tartar on medium speed until foamy. Gradually add the remaining 1/4 cup sugar and beat on high until stiff, glossy peaks form.
Combine. Fold one-third of the egg whites into the yolk batter to lighten it. Then gently fold in the remaining whites in two additions, keeping as much air in the batter as possible.
Bake. Pour the batter into the ungreased tube pan and smooth the top. Bake for 32–37 minutes, until the top is golden and a toothpick inserted in the center comes out clean.
Cool inverted. Immediately invert the pan onto its legs or over the neck of a bottle. Let the cake cool completely upside down, about 1 hour. This prevents the sponge from collapsing.
Unmold and serve. Run a thin knife around the edges and center tube to release. Transfer to a plate, dust with powdered sugar, and serve with whipped cream and orange slices if desired.
