Am I expecting too much from ermine buttercream?
I love the light texture and not overly sweet qualities of ermine. It tastes the best to me out of all the frostings I've tried.
Unfortunately, I want to make intricate lambeth style cakes with crisp piping and very smooth sides. I tried to do this with the ermine frosting a couple of times, but either the smoothing takes like 40 minutes (freeze, smooth, freeze, smooth) and the result isn't as smooth as I'd like. It seems to be a universal problem, because I searched online and I've never seen a smooth ermine cake. I have tried King Arthur's ermine recipe and Sugarologie's ermine (both regular flour and tapioca starch). While tapioca is much easier to work with, it still pipes less defined details and doesn't smooth well.
Swiss merengue is amazing for smoothing and piping details, but is quite sweet and heavy for my taste as well as my friends'
I'm starting to wonder if my ideal cake is impossible. Am I expecting too much from ermine? Should i just use it for filling and SMBC for the exterior and piped details?
