Mousselinebuttercream Recipes

Steps:

• In a mixing bowl beat the butter until smooth and creamy and set aside in a cool place.
• Have all other ingredients at room temperature.
• Have ready a heatproof pouring container ready for the sugar syrup.
• In a small heavy saucepan heat 3/4 cup sugar and the 1/4 cup water, stirring constantly, until the sugar dissolves and the mixture is bubbling.
• Stop stirring and reduce the heat to low.
• (If using an electric range remove from the heat.) In the bowl of a stand mixer unsing the whisk attachment, beat the egg whites until foamy, add the cream of tartar, and beat until soft peaks form when the beater is raised.
• Gradually beat in the remaining 1/4 cup sugar until stiff peaks form when the beater is raised slowly.
• Increase the heat and boil the syrup until the thermometer registers 248'F to 250'F (the firm ball stage).
• Immediately transfer the syrup to the heatproof container to stop the cooking.
• Pour a small amount of syrup over the whites with the mixer off.
• Immediately beat at high speed for 5 seconds.
• Stop the mixer and add a larger amount of syrup.
• Beat at high speed for 5 seconds.
• Continue with the remaining syrup.
• For the last addition, use a rubber scraper to remove the syrup clinging to the heatproof container.
• Lower speed to medium and continue beating up to 2 minutes or until the bottom of your mixing bowl feels cool to the touch.
• If not completely cool, continue beating on lowest speed.
• Beat in the butter at medium speed 1 tablespoon at a time.
• At first the mixture will seem thinner but will thicken beautifully by the time all the butter is added.
• If at any time the mixture looks slightly curdled, increase the speed slightly and beat until smooth before continuing to add more butter.
• When butter is fully incorporated you may add any of the optional flavorings.
• Place in an airtight bowl.
• Rebeat lightly from time to time to maintain silky texture.
• Buttercream becomes spongy on standing.
• Will keep 2 days room temperature, 10 days refrigerated, 8 months frozen.
• Allow to come to room temperature completely before rebeating to restore texture or it will break down irretrievably.

Steps:

• Combine the sugar and meringue powder in a stainless steel bowl and whisk to combine. Mix egg whites and corn syrup. Combine the egg white mixture with the sugar mixture and whisk vigorously. Heat mixture over a hot water bath, stirring occasionally. The meringue is ready when the sugar is dissolved. Whip in a mixer fitted with a whisk attachment for 10 to 15 minutes. Slowly add the cool, room temperature butter and shortening. Add the vanilla seeds and then fold in the crushed cookies.
