When I examined my Easy Cookie Press Cookies the day after decorating them and found that the icing had not set, I was cursing the Texas humidity. It had just wreaked some havoc on my Sugar Cookie Recipe and now every cookie I touched was sporting a crushed icing look that I was not fond of.
Well, unless you skipped this post’s title and first line, you know what’s coming. The humidity wasn’t to blame for my icing woes… I was! The almond extract I used in my icing recipe had oil in it. Doh!
What have I learned from this mishap? Any tiny bit of oil that makes it into a royal icing recipe will cause the structure of the icing to break down. So, any flavorings used must have an ingredient list free of oils. Mixing utensils and containers that are glass or metal must be washed in hot soapy water prior to use. Most shockingly, any plastic spatulas or bowls that are used should be designated as “only for icing”. Oil will bond to plastic and can never be completely removed.
