Raspberry Fruit Extract: A Great Flavor Enhancer! Red, ripe raspberries are treasured for their delicate flavor. Pureed and strained they make a wonderful coulis (a sauce made from pureed fruit). As a finishing touch on cakes they are superb. As is the case with so many fruits and vegetables their origin is crucial to quality and taste. Washington and Oregon are especially noted for their outstanding red raspberries. It is these raspberries that are carefully selected and concentrated for this red raspberry extract. The bright, delicious extract can be used wherever you want to increase the intensity of your raspberry flavor. Add it to your pies, fruit salads, cobblers and add a little to your next coulis. You can also mix it into your raspberry jam to, as the old saying goes, kick the flavor up a notch.
