I'm venturing into the world of organic baking and I'm looking for a buttercream that I could use for decorating cakes. I've been using the Sugarshack recipe because it tasted good and was easy to work with and smooth. But since I can't get organic hi-ratio shortening, does anyone have any recommendations for a buttercream recipe that could be converted to organic ingredients and is easy to ice and smooth on a cake (and possibly hold up in the warmer weather). Any help would be great.
