I am making this cake for T-day: http://cookingbythebook.com/blog/reci... It involves a boiled flour buttercream icing I've never done before.
If it were conventional buttercream I'd make it today and put an airtight container of it in the freezer to ice the cake on Wed evening. But this boiled icing is unfamiliar to me.
Can I freeze away or should I wait until Wed. to make it keeping in mind that I'll be doing pies and a considerable amount of other things on Wed?
Thanks in advance.
