A few things to do with raspberries:
1-1/2 cup white wine vinegar
1-1/2 cups raspberries
1/2 cup granulated sugar
Put raspberries and vinegar in a 1 quart jar. Seal jar and let stand in a sunny window 4 days. Strain vinegar in a small stainless steel enamel saucepan then discard berries. Stir in sugar and heat over medium heat until mixture comes to a boil. Simmer over low heat for 10 minutes. Cool and pour into pint bottle. Cover and store in a cool dry place or store in the refrigerator.
an easier way
4 c red raspberries
4 c white wine vinegar
Combine in a glass jar and let the raspberries macerate (sit, steep, etc) for two weeks.
Turn the jar every day to help mix the ingredients.
Good for a vinaigrette or marinade, etc.
Or here's something sweet:
1 pint fresh raspberries
1 tablespoon fresh lemon juice
1 cup heavy cream
1 egg white
1/4 cup sugar
1. Place raspberries in blender container and blend until smooth.
2. Add lemon juice.
3. In large bowl beat cream until soft peaks from then fold in raspberry mixture.
4. Sprinkle sugar over egg white and continue beating until sugar is dissolved then fold into raspberry mixture.
5. Spoon into parfait glasses then cover and freeze.
6. Remove from freezer 15 minutes before serving.
Then there's the good old smoothie.
Endless variations--throw in a blender: some raspberries, milk, yogurt (regular or frozen), sorbet, a banana, ice, maybe some sugar or honey or artificial sweetener, orange juice, other kinds of berries, etc. Whatever combination of stuff you have that sounds good. Sometimes they aren't quite as fantastic as you imagine, but it's fun experimenting.
