Prepare as above, except omit the 1/2 of a 6-ounce can (1/3 cup) frozen lemonade concentrate. Substitute 2 cups fresh or frozen unsweetened strawberries. If using fresh strawberries, remove stems and caps. For frozen strawberries, thaw the berries after measuring; do not drain. In a blender or food processor, add strawberries. Cover and blend or process until smooth. Set a fine mesh sieve over a bowl. Strain strawberries through the sieve; discard the seeds. Stir orange juice concentrate, strawberry puree and vanilla into egg mixture. Complete as directed. If you like, substitute strawberry ice cream for the vanilla ice cream. Garnish each glass rim with a whole strawberry that's been split lengthwise.
