Mojito Cupcakes - Part 2: Lime Italian Meringue Buttercream

The light and silky Italian Mergingue Buttercream is a stark contrast to the mainstream buttercream recipes that are rich and heavy. It is commonly used in Wedding cakes, and preferred by many professional bakers. It is the most stable and resilient to heat, compared to the other buttercream varieties.  Finally, it tastes so delicious, that you'll never want to make another frosting with powdered sugar!

Warren Brown from Cakelove has a fabulous instructional video about making the Italian meringue butter cream.  He is very good at articulating the important points.  I still managed to mess up five batches before making it correctly, and decided to include a Tips section to share my findings.  His advice is succinct, yet profound - "Do not overwhelm, do not underwhelm.  Take your time."  I couldn't agree more, and the final product is worth the precision.  If you have not made this type of frosting before, please watch the video.

TIPS

1. Do not use pasteurized egg whites, as they will not whip to the firm peak stage. 
1. Alternatives
1. Meringue/egg white powder
2. Pasteurized eggs (in the shell)
2. Anything that touches the egg whites must be extremely clean, and free of any residue.
3. Use a copper bowl.  If you do not have one:
1. Add the cream of tartar to the raw egg whites
4. Please check out Baking911's tips on making meringues and Italian meringue butter cream frosting.

INGREDIENTS
Meringue
5 room-temperature egg whites
pinch salt
1/2 tsp cream of tartar (if not using a copper bowl)
2 ounces (1/4 cup) castor sugar

Syrup
8 ounces (1 cup) castor sugar
1/4 cup water

Butter, 1 lb., unsalted, and soft

Lime
1-2 tsp Lime oil or 
1/2 cup Lime curd  (recipe to follow)

DIRECTIONS

1. In a sauce pan, combine 8 oz of sugar and 1/4 cup water
1. Wisk and put on medium heat with a thermometer to monitor the temperature
2. Remove from the heat when thermometer reads 240 (sea level)
1. If sugar syrup approaches 230 prior to the egg white mixture's completion, turn off the heat and cover the sauce pan
2. Warm syrup up to 240 when egg white mixture is ready for the syrup
2. In a large mixing bowl, add egg whites and cream of tartar (if needed) and begin with a wire whisk attachment on medium/medium-low speed
1. Stage 1: Raw

2. Stage 2: Foamy

1. 
   
3. Stage 3 - Soft Peak: Increase mixer speed to Medium High

1. The peaks droop slightly
4. Stage 4 - Hard Peaks: Increase mixer speed to High

1. Mixture is smooth, moist and shinny.  If the beaters are stopped and lifted, straight peaks should form.
5. Begin to add extra 1/4 cup sugar slowly as mixture transitions from Hard Peaks to Firm Peaks
6. Stage 5 - Firm Peaks: Mixer is on highest speed

1. Egg whites are think, volumnious and glossy
3. When egg whites have reached the stiff peak state, change focus to the sugar syrup.
1. Syrup
1. The syrup needs to reach the 240-245 degree mark
2. If the syrup was removed from heat
1. Turn on medium to medium-high heat
2. Monitor syrup, and remove from heat as temperature reaches 240-245 degrees F
2. Add the sugar syrup to egg whites very slowly, aiming for the area between the beater and the side of the bowl
1. Watch above video for technique
2. Bowl should be warm 
3. Beat for 7 - 10 minutes
1. Outside of bowl should be room temperature
4. Slowly add the butter
1. Add 1-2 tablespoons at a time

Mojito Cupcakes - Part 1: Rum soaked cakes, Rum Sauce and Mint Creme Filling

The first step to creating a Mojito cupcake is creating the cupcake base: a rum soaked rum cupcake. The recipe is adapted from two recipes, and requires creating the butter rum sauce while the cupcakes are baking.  When soaking the cupcake, is it important to detach the liner from the cupcake to allow the rum sauce to seep into the bottom of the cakes.    It is helpful to use the Reynolds Stay-Brite foil liners, as the liner detaches easily and retains an elegant shape.  Paper liners are discouraged because they don't retain their shape when loosened, and regular foil tends to rip.  


In the photo below, the Stay-Brite liner is on the left, and regular foil on the right.  Notice that the Stay-Brite wrapper almost appears as though it wasn't completely detached from the cupcake!  The monkey patterned liner  was love at first sight for this blogger.

The Mojito cupcake utilizes a Lime Italian Meringue Buttercream frosting, Mint creme filling, and a fresh mint leaf for garnish.  This recipe creates about 24 cupcakes.


Rum Soaked Rum Cupcakes


INGREDIENTS


1 cup (2 sticks) butter, softened
2 cups sugar
4 eggs
3 cups cake flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
3/4 cup buttermilk
1 teaspoon vanilla
1/2 cup dark rum


DIRECTIONS

1. Preheat oven to 300 degrees F. 
1. Line cupcake tins with foil liners.
2. Cream butter and sugar until fluffy. 
1. Beat in eggs and mix completely. 
3. Whisk together flour with baking powder, baking soda and salt. 
4. Gradually beat flour into butter mixture, alternating with buttermilk and vanilla. 
1. Stir in dark rum and Triple Sec.
5. Spoon batter into prepared cupcake tins and bake in 300 degree oven for 16-20 minutes. 
1. Cakes are done when it lightly springs back after you touch it with your finger. 
6. While cupcakes are still warm, use a regular teaspoon to drizzle rum sauce all over each cupcake.
1. Loosen the liner to allow sauce to soak into the bottom.
2. Use between 1-2 teaspoons per cake.
7. After cupcakes have completely cooled, refrigerate for an hour.
8. Fill each cupcake with about 1 tsp of mint creme.
1. I use a squeeze bottle, but a small spoon works just as well
2. If using a spoon, make the opening as small as possible.
9. Frost and refrigerate
10. Take out for about 30 minutes prior to serving, however cupcakes can't be left at room temperature for long if the mint creme is used because it will spoil.
