Limoncello Tiramisu

Serves 8-10

I saw this recipe in the Wall Street Journal about a year ago. It inspired me to duplicate it in a kosher version for Shavuous. If you like lemon, this one is for you! It’s worth the effort.

5 large eggs
1 cup sugar
1½ cups limoncello

Juice of 6 Meyer lemons, plus zest of 3 Meyer lemons (if you cannot find Meyer lemons – most will not be able to find them, use regular lemons and extra zest)

1 cup water
2 cups mascarpone, at room temperature
40 ladyfingers

Make zabaglione: Set a metal bowl over a pot to create a double boiler. Add enough water to pot to reach just below bottom of bowl. Separate eggs, putting yolks in bowl of double boiler and setting whites aside. Beat yolks with ¼ cup sugar and ½ cup limoncello. Heat water in double boiler to a steady simmer. Whisk egg mixture until thick enough to form a ribbon when you lift whisk, about 5 minutes. Remove bowl from heat and let zabaglione cool.

Meanwhile, pour remaining limoncello, ¾ cup lemon juice, 1 cup water and ½ cup sugar into a saucepan. Bring to a boil and cook, stirring, until sugar dissolves and mixture thickens, 5 minutes. Let syrup cool.

In a large bowl, stir mascarpone to soften, then add zest and whisk until light and creamy. Using an electric mixer, whip reserved egg whites with remaining ¼ cup sugar until mixture holds moderately firm peaks, about 3 minutes.

When zabaglione is cool, use a rubber spatula to fold a third of it into mascarpone. Fold in remaining zabaglione in two or three additions, then fold in whipped egg whites in several additions. Stir gently until mixture is light and evenly blended.

Fill a shallow bowl with cooled syrup to ¼-inch deep. One at a time, roll ladyfingers in syrup and transfer to a 9-by-13-inch baking dish. Arrange moistened ladyfingers in tight rows to form a single layer of about 20 ladyfingers. Trim edges to fit.

Spread half mascarpone mixture over ladyfingers. Repeat to form second layers of ladyfingers and mascarpone mixture.

Cover tiramisu with plastic wrap and refrigerate at least 6 hours or up to 24.

  1. Seriously, one of the best things I’ve ever made. I’ve been eating it all week!

  2. This sounds amazing. I plan to try it with Sukkah Hill Spirits’ Etrog and Besamim Liqueurs this year. Thanks for a great idea!

    • Mascarpone is dairy. I love it but it is a dairy ingredient. You can try and use Tofutti sour cream with about 2 tablespoons confectioners’ sugar mixed in as a substitute.

    • This does not freeze well but can be made up to 3 days in advance and it keeps well in the refrigerator. I make it on Shavuos every year and its one of my all time favorites. I eat all the leftovers!
