When peeling the meringue off the parchment paper, carefully lift it so it comes out in one piece. Don’t peel it to early, it will break. Or too late, it will definitely crumble. Test it — lift one corner a little at a time. You’ll know when it’s ready because it should give pretty easily. And if it cracks, no worries. You will cover it with buttercream and cashews and nobody will ever know! It will still be a very delicious cake.
