Combine raspberries, raspberry jam and orange flavored liqueur together and mix well. If you are using frozen raspberries you may need to add a small amount of sugar to this mixture if the jam doesn't sweeten it enough. Alternate layers of angel food cake followed by raspberry mixture and then vanilla yogurt in parfait glasses. Top with whipped topping and slivered almonds.
Fat free yogurt and whipped topping may be substituted.
Make other fruit parfaits by changing the type of jam and fruit used.
