Ingredients:
- 4 cups (480 g) sifted Confectioner’s Sugar (Icing Sugar)
- 3 tablespoons (45 ml) Meringue Powder
- 1/2 cup (120 ml) Warm Water (Starter)
- 1 teaspoon (5 ml) Clear Vanilla Extract
- 1–3 teaspoons (5–15 ml) Lemon Juice or Water (Adjuster)
Instructions:
- Sift the confectioner’s sugar and meringue powder together into a large, clean mixing bowl. This step is non-negotiable for smooth icing.
- Add the warm starter water and clear vanilla extract to the dry ingredients. Mix on the lowest speed until just combined. The mixture will look thick and pasty.
- Beat the mixture on low speed (Speed 1-2 on a stand mixer) for 1 minute to fully incorporate the liquid.
- Increase the speed to medium (Speed 4-6). Beat for 5 to 7 minutes until the mixture becomes noticeably thicker, increases slightly in volume, and turns a brilliant, opaque white.
- Test for Stiff Consistency (Piping): The icing is ready when you can pull the paddle away and the peak stands straight up without flopping over. This is your base stiff piping icing.
- Immediately transfer the bulk of the stiff icing into an airtight container and cover the surface directly with plastic wrap or a damp cloth to prevent drying.
- Adjust for Medium (Outlining): Take a small portion of the stiff icing and add water or lemon juice, one tiny drop at a time, stirring until the desired consistency is reached (peaks should curl slightly).
- Adjust for Flooding (Filling): To create flooding icing, continue adding small drops of water until the icing holds the “10-second rule” consistency: when stirred, the gap should completely disappear and become smooth in 8 to 12 seconds.
- If colouring, use highly concentrated gel paste colours, not liquid food colouring. Use immediately for decorating.
