I had a whole huge list of things I was going to do yesterday: AMMI had free admission, the San Gennaro festival is going on, we need groceries and cash. But it was one of those days, in the mid-70s so you don't feel justified turning on the air conditioner but the humidity hovers around 100 percent so you feel like your slugging through a swamp just walking down the block.
But I did turn on the air and use this. I've been intrigued by the idea that you can bake a cake on a baking sheet . We call it a "rimmed baking sheet" at work, I presume because the jelly roll is not as common a dessert as it once was, so new cooks might be confused by the term "jelly-roll pan." Anyway, I made a basic jelly roll yesterday, and it wasn't pretty coming out of the oven, although it didn't look too bad once it was assembled.
Haven't tried it yet, but Todd didn't rave. I think I'll spread it with ice cream next time - the best thing about the birthday cake is eating it with ice cream, a creamy contrast to the spongey crumb of the cake. I make sure I get a little bit of each with every bite.
Anyway, the cake recipe:
I lined the pan with foil and sprayed it with nonstick spray, which worked OK but not perfectly (the edges of the foil sort of curled up as the cake shrunk while baking, making it hard to remove without getting some cake with it). First you mix 1/2 cup flour with 1 teaspoon baking powder in one bowl. Separate 4 eggs into 2 bowls (yolks in a medium bowl, whites in a large one). Add 1/3 cup sugar and 1/2 teaspoon vanilla to the egg yolks and beat for 5 minutes, until they're creamy. (The recipe called for beating the yolks with the vanilla, then adding the sugar, but I made a mistake. It didn't seem to make a difference.) With clean beaters, whip the egg whites to soft peaks, then add 1/2 cup sugar and whip to stiff peaks. Fold in the yolk mixture, then the flour mixture. Spread in baking sheet and bake at 375 degrees for 12 to 15 minutes.
Turn out of pan immediately onto a clean kitchen towel dusted with confectioners' sugar. Roll the cake up together with the towel and set on a rack to cool. Once it's cool, unroll it and spread the filling (I used 1/2 cup cherry preserves mixed with some Cointreau) in center, leaving a 1-inch border without. Roll up and trim the edges.
