4. Strike off the excess product so
it is even with the top of the container

5. Use the following formula to
figure overrun percentage:
"Weight of liquid mix minus weight of
frozen product/divided by the frozen
weight. Multiply by 100." See example.
Example:
Weight of 1 pint of mix
Weight of 1

provide a scale (P/N HC158049) that is
graduated in overrun percentage.

NOTE: Rerun product is unable to
accept the same amount of air as
fresh product. As a result, the quality
will be affected and product may
appear grainy and icy.
