Raspberries are often extremely infested. They are nearly impossible to clean without ruining the fruit. Proper inspection requires exceptional patience. Currently, fresh raspberries and blackberries are not permitted in OU certified catering facilities and restaurants. For instructions on insect inspection of raspberries, please see “Special Instructions” below:
1 10-ounce package frozen red raspberries in syrup, thawed
1 750-ml bottle sweet white wine (zinfandel), chilled
1/4 cup raspberry liqueur
Place raspberries and syrup in a blender container or food processor bowl. Cover and blend or process until berries are smooth. Press berries through a fine-mesh sieve; discard seeds (you should have about 3/4 cup sieved puree). In a pitcher combine raspberry puree, wine, and raspberry liqueur. Serve over ice, if desired.
Raspberries Insect Inspection:
Due to the very delicate nature of raspberries, they cannot be placed in water nor may they be extensively handled. Therefore, we recommend the following procedure as the most practical and effective way of checking raspberries.
1. Stretch a white cloth or sheet of white freezer paper over a light box oron a countertop with ample overhead lighting. Raspberries should be dropped one by one onto the white surface. This will dislodge at least some of the insects that may inhabit the berry.
2. If two or more insects are found, a pint of berries is to be considered infested and may not be used. There is no washing procedure that will guarantee removal of all of the insects.
3. If after dropping the berries no insects are found, the berries should be visually inspected one by one. Pay careful attention to the cavity of the berry where insects often hide.
4. When working in a catering commissary, a larger amount of berries can be dropped on a light box at one time, minimizing the time of inspection.
Alternative method: recommended for large quantities
1. After following steps 1 & 2 above, berries should be placed in a container of soapy solution (prepared with food grade detergent) and agitated vigorously.
2. After a thorough rinsing, the berries may be spin-dried.
3. To verify that the washing has succeeded in removing all insects, check 5 berries per pint in the manner outlined above.
