准备

烤海绵蛋糕：

• 将架子放在烤箱的中间，然后将烤箱加热至350°F。轻轻涂一个9英寸的蛋糕锅，然后用羊皮纸在底部排成一列。将面粉，玉米淀粉和2汤匙筛选在一起。糖。将鸡蛋和蛋黄打碎到电动搅拌机的碗中。以中等速度鞭打，加入柠檬汁，盐和剩余的6汤匙。糖。将速度提高到高，鞭打，直到鸡蛋非常蓬松，至少在体积上增加了两倍，并形成3至4分钟的软峰。从搅拌机上取下碗。将面粉混合物在鸡蛋上筛选三个单独的添加剂，每次都会轻轻搅拌。 Put the melted butter in a small bowl, add a dollop of the batter, and stir gently. Add this to the mixing bowl, folding gently with a spatula to incorporate. Scrape the batter into the prepared pan. Bake until dark golden and springy when touched, about 40 minutes. Cool the cake in the pan on a rack.

制作柠檬慕斯：

• In a heavy-duty, nonreactive saucepan, combine the egg yolks, sugar, lemon juice, and butter. Cook over medium heat, whisking constantly until the butter melts. Reduce the heat to medium low and stir constantly with a wooden spoon until the mixture thickly coats the back of the spoon, about 5 minutes. Strain into a clean bowl and stir in the zest and salt. Refrigerate, covered, until completely chilled. The mixture will be very thick. In a medium bowl, mash the mascarpone with a rubber spatula. Add a little of the chilled lemon curd and continue mashing until the mixture is lump free. Stir in the rest of the lemon curd, and then fold in the whipped cream. (If the mousse is too stiff, add a touch of unwhipped heavy cream to loosen it.) Refrigerate until it’s time to assemble the trifle.

混合浸泡液体：

• In a small saucepan, combine the sugar and water. Cook over medium heat, stirring constantly, until the mixture boils and the sugar has completely dissolved. Set aside. Pass 1 cup of the berries through a food mill fitted with a fine disk or force them through a fine sieve, mashing with a wooden spoon, into a medium bowl. Discard the contents of the strainer and stir the purée (you should have about 1/2 cup) into the sugar syrup. Add the lemon juice and set aside until it’s time to assemble the trifle.

Assemble the trifle:

• 用锯齿刀将蛋糕切成三层相等的圆层。（如果您使用的是酒杯，请将图层切成正方形。将一个蛋糕层放在底部。用糕点刷，用浸泡液使蛋糕很好地弄湿蛋糕（应该很好地湿润但不要湿润）。

• Spread on one third of the mousse and then arrange one third of the remaining 4-1/2-cups berries over the mousse. Place the second cake layer on top, moisten it with more soaking liquid, and repeat with another third of the mousse and another third of the berries. Do a third layering, ending with the remaining berries arranged on top (save the best-looking berries for this layer).
  

• 冷藏琐事，直到慕斯牢固至少3个小时，但不超过一天。在食用之前，请在蛋糕上卸下蛋糕或戒指，然后将小琐事像蛋糕一样切成薄片。
