Step 1: Sift the Powdered Sugar

• Sifting prevents lumps, ensuring a silky-smooth texture.

Step 2: Add Wet Ingredients

• Whisk in milk 1 tbsp at a time until reaching a thick but pourable consistency.

Step 3: Flavor & Shine

• Stir in vanilla and corn syrup (if using). For fruit-flavored icing, replace vanilla with 1 tbsp fruit jam.

Step 4: Adjust Consistency

• Too thick? Add more milk drop by drop. Too thin? Mix in extra powdered sugar.

Step 5: Drizzle & Serve

• Spoon over warm strudels, or use a piping bag for neat lines.
