The classic Italian rainbow cookies are made with tinted layers of an almond-paste flavored cookie dough that, after baking, is spread with seedless raspberry preserves and then weighted to seal the layers. The cookies are then divided into long strips, coated with melted dark chocolate, and cut into slices.–Carole Walter
Italian Rainbow Cookies
- 12 ounces (1 1/2 8-ounce cans) almond paste
- 1 cup unsalted butter slightly firm
- 1 cup sugar
- 4 large eggs separated
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour spooned in and leveled or 1 1/2 cups sifted matzo cake meal, spooned in and leveled
- 1/2 teaspoon salt
- 6 to 8 drops green food color
- 8 to 10 drops red food color
- 1/4 cup seedless raspberry preserves
- Up to 1 cup apricot preserves
- 10 ounces semisweet chocolate coarsely chopped
Make the layers
- Position the oven racks in the upper and lower thirds of the oven. Heat oven to 350°F (175°C). Lightly butter the bottom of three 12 1/4 x 8 1/4 disposible aluminum baking pans or three 1/4 sheet pans. Line the pans with parchment paper, then butter the parchment and the sides of each pan.
- Break the almond paste into pieces and place it in the work bowl of a food processor fitted with the steel blade. Process for 10 to 15 seconds, or until finely chopped. Alternatively, shred the almond paste on a box grater.
- In the bowl of an electric mixer fitted with the paddle attachment, mix the butter on medium-low speed just until smooth. Increase the speed to medium, add the grated almond paste, and beat until lightened in color, about 2 minutes. Pour in the sugar in a steady stream, beating for 1 minute longer. Then add the egg yolks and the vanilla, beating well to combine. Scrape down the bowl as needed.
- Combine salt and flour, and at low speed blend in three additions, just until incorporated.
- In a clean mixer bowl, using the whip attachment, beat the egg whites on medium speed until frothy. Increase the speed to medium-high and continue beating until firm peaks form. Using a large rubber spatula, gently fold 1/3 of the egg whites into the batter to lighten the mixture, then fold in the remaining egg whites in two more additions.
- The batter should actually be a stiff dough.
- Divide the batter into thirds (each measuring approximately 1 2/3 cups) and place into three separate bowls.
- Tint one portion with the green food coloring, blending until evenly colored. Tint another portion with the red food coloring, again blending until evenly colored. The remaining batter is not colored.
- Spread the batters in the pans, using a small offset spatula to push the stiff batter into the corners of the pan and smooth the surface. Be sure the batter is evenly distributed, especially into the corners of the pans. If the batter is tricky to spread, try lightly wetting the back of the spatula with a very small amount of water.
- Bake the cakes for 10 to 12 minutes, or until the tops are firm to the touch but not browned. (If you’re going to err with the baking time, it’s actually better for the cakes to be slightly underdone as opposed to overdone.) Let the cakes rest in the pans on wire racks until cool enough to handle, then invert each pan and peel off the parchment.
Assemble the layers
- Have ready a large sheet of plastic wrap placed on a cookie sheet. Invert the green layer onto the plastic, top side down. Using a small offset spatula, spread the surface evenly with 2 tablespoons of the raspberry preserves. Place the plain layer, again top side down, on top of the raspberry preserves. Align the two layers and press them together. Spread 2 tablespoons of the raspberry preserves over the plain layer, again using a small offset spatula. Then place the pink layer, top side up, on top of the raspberry preserves. Be sure that the three layers are evenly aligned, then press them together again.
- Wrap the layered stack tightly with plastic, sealing the ends securely, and place it on a clean cookie sheet.
- Place another cookie sheet on top of the wrapped stack and weight it with two or three heavy cookbooks to compress the layers. Let the stack rest at room temperature for at least 24 hours, turning it over once or twice during the weighting period.
Glaze the layers
- Unwrap the stack and set it on a cutting board. Using a large serrated knife, trim 1/4 inch from all sides.
- Then cut the stack into five equal strips, each measuring approximately 1 1/4 inches wide. Separate the strips and place them on a large wire rack set over a cookie sheet. (If desired, spray the rack with vegetable cooking oil spray or slick it with a paper towel ever so gently damped with a neutral cooking oil.)
- To make the apricot glaze place the apricot preserves and 2 tablespoons water in a small saucepan. Bring to a boil, then simmer for 1 minute. Pass through a fine strainer into a bowl and discard the pulp. This can be made ahead and reheated just before using.
- Brush a thin layer of the warm glaze on the top and sides of each strip to seal the surface. Chances are you won't use all the glaze. Let stand for 1/2 hour or longer.
- When ready to coat the strips, fill a medium pot with 1 inch of water and bring it to a simmer. Place the chocolate in a large bowl and set it over the simmering water to melt, gently stirring occasionally with a rubber spatula. Watch carefully! The chocolate should not become too hot. When the chocolate is almost melted, remove it from the heat and allow it to stand until it is completely melted. Gently stir occasionally. It is ready to apply when it is smooth, tepid, and the consistency of chocolate syrup. (Note: If the chocolate becomes too thick, warm it over simmering water until it reaches the correct consistency.)
- Working one strip at a time, spoon about one-fifth of the melted chocolate down the length of the strip. Using a small offset spatula, spread the chocolate evenly over the top and sides, taking care to smooth all surfaces. Repeat with the remaining strips. Let the strips stand at room temperature until the chocolate hardens. This can take up to several hours, depending on the temperature of the room and climate conditions. Cut each strip into 5/8-inch slices.
StorageStore in an airtight container, layered between strips of wax paper, for up to 3 weeks. (Note: These cookies may be frozen, preferably before slicing.) This cookie improves with age.
Recipe Testers’ Reviews
These Italian rainbow cookies are wonderful. Let me elaborate. Yes, these require a good amount of effort, expensive ingredients, three pans, several mixing bowls, food coloring, chocolate, and more than one afternoon for preparation, but the outcome is well worth it. I’ve made these cookies both with flour and with matzah cake meal so that I could serve them during Passover, and each time they turned out great. There was no significant difference between the two. These are a far cry from the dried out commercial versions of this cookie. I weighed the batter into equal portions before adding food coloring so the layers would be even. (Yes, I do obsess when I bake.) This batch remained weighted down for almost 48 hours as I was away for the weekend and it didn’t hurt the cookies one bit. There was a lot of apricot jam left over after I brushed the cookie with it, so next time I would cut it back by half.The first time I made these, I used the lesser amount of food coloring but the color was not intense enough and this time I used even more food coloring than the recipe suggested in order to get the intense colors that I have seen when I have purchased these in bakeries.These hold well in an airtight container and really do improve with age. I froze the leftover cookies (hardly any because everyone wanted to take some home.) They remained fresh and delicious even after freezing. I used the food processor to mix the almond paste rather than a grater. Read the recipe carefully and don’t let the multiple steps overwhelm you…go slowly and step by step and the rewards will be amazing.
