Earl grey and strawberry cakes

Posted on Aug 13, 2017 by in Recipes | 6 comments

Swiss meringue buttercream can be a cruel mistress. She’s temperamental, she’s sensitive and she can smell your fear.

Getting swiss meringue buttercream wrong can be a complete disaster (trust me, I have been on the receiving end of some pretty horrible separated and eggy tasting buttercream). On the other hand, getting it right is so so good.

To me, swiss meringue buttercream is the perfect cement for any layer cake. I find that it is never too sweet or overpowering. While delicious in its own right, it also has an amazing ability to simultaneously compliment yet allow any cake to shine.

While I would never presume to know everything about this delicate substance, I have picked up a few tricks and tips over the years. I hope that these assist you the next time you attempt to tame the swiss mistress.

  • Mix the ingredients: It is important to mix the egg whites and sugar well when you place them into the stand mixer bowl, as well as intermittently while the mixture is heating. If you don’t, you are likely to end up with little bits of cooked egg white in your buttercream (blerrrghh).
  • Temperature is key: The temperature of your butter can make or break your buttercream. If your butter is too cold, the buttercream will curdle. If it is too hot, your buttercream will be ‘soupy’ in consistency. Luckily, this is easy to fix.If your butter is too cold and the mixture has split, take a small amount of the buttercream out of the bowl, place it in a microwave proof bowl and heat it for a few seconds in the microwave. Add the melted buttercream back into the mixture and combine well. If your buttercream is ‘soupy’, place the stand mixer bowl into the refrigerator for a few minutes. Once the mixture has cooled, place the bowl back on the stand mixer and combine well.
  • Patience is essential: The temperature of the egg while and sugar mixture will probably fluctuate quite a bit before reaching 70 degrees. DO NOT GET FRUSTRATED. It is crucial that the egg whites be heated to this temperature before proceeding. It will happen eventually. Trust me.
  • Just keep mixing: Occasionally, swiss meringue buttercream will attempt to trick you by appearing to curdle. If your butter is at the right temperature, JUST KEEP MIXING. The buttercream will usually come back together within a few minutes.
  • Your complete attention is required: If you are new to the quest of the swiss meringue buttercream, do not expect that you will be able to multi-task. When you are making swiss meringue buttercream for the first few times, it is important that you are paying attention to the temperature and the consistency of the buttercream at all times.

Now, if you are feeling a little too intimidated to attempt a layer cake covered with swiss meringue buttercream, you may find it helpful to start smaller with some earl grey and strawberry mini cakes.

While I am proud of all my recipes, I think this one is particularly exciting. The sweetness of the swiss meringue buttercream is complimented by the slight tartness of the strawberry coulis. The earl grey tea flavour cuts through the richness to make a really delicious and refreshing treat.
