When choosing berries, look for those that are medium sized and uniform in color. They should also feel solid to the touch and not be leaking juice.
In saucepan, place gelatin and water. Stir until dissolved and then add fruit and extracts. Heat to a simmer, stirring gently for 10 minutes until the raspberries dissolve. Pour liquid into eight-inch by eight-inch by two-inch pan and let cool. When cool, add nuts. When Jellied Fruit Salad has set, place in four serving dishes and garnish with mint leaves.
