Common Mistakes to Avoid
Making sugar cookie icing that hardens can be tricky if you’re not careful. Here are some common mistakes to avoid:
- Not sifting powdered sugar: Failing to sift the powdered sugar can lead to a lumpy icing. Always sift before mixing for a smooth consistency.
- Using too much liquid: Adding excessive milk or water will result in runny icing. Start with less and gradually add more until you reach the desired thickness.
- Ignoring temperature: Icing set at room temperature may not harden properly if it’s too humid. Ensure your workspace is dry and cool for best results.
- Rushing the drying time: If you try to move cookies before the icing has completely hardened, it can smudge. Allow ample time for the icing to set—typically a few hours.
- Overmixing: Stirring too vigorously can incorporate air bubbles, which may affect the icing’s smoothness. Mix gently until just combined.
