Blackberry souffle dessert

We used up the blackberries in this blackberry soufflé. It tasted like sherbet. Delicious, low in calories and so easy to make!
After looking for online recipes, we took an average of all of them. We think the secret is to get the egg whites very stiff. Then mix a third of the egg whites into the blackberry mixture, and then fold in the rest. Try to knock out as little air as possible.
Calories... it's Saturday, we have a full allowance!! Having said that, there are probably around 250 calories each...
