While holding the bag with one hand, fold down the top with the other hand to form a generous cuff over your hand as shown.
With an angled spatula, fill the bag with approximately 1/2 cup of icing.
Note: It is important not to overfill the bag; otherwise, excess icing may squeeze out the wrong end.
Remove icing from the spatula by squeezing the bag with your thumb and fingers against the spatula and pulling spatula out.
Close the bag by unfolding the cuff and twisting the bag closed. This forces the icing down into the bag.
Make sure you release any air trapped in bag by squeezing some of the icing out of the tip into the bowl. This is called "burping" the bag.
