GOT THIS RECIPE FROM ANOTHER FORUM AND JUST MADE IT. IT WAS LOVELY. I WILL COPY AND PASTE IT
(THIS IS FROM DUKANER FORUM by LADYMEBA)
I used a ratio of 5 or 6 heaped tablespoons of yogurt to 1 little teaspoon of jelly (jello) crystals - don't forget to dissolve them in a little hot water before adding to the yogurt.
When the hot, jelly water has cooled add it to the yogurt and stir well.
Place in the freezer and set your first alarm for 25 - 30 minutes.
When the alarm goes off take the yogurt out and really stir well to get rid of as many water crystals as possible.
Rinse and repeat... and repeat...
Mine took about 4 hours but it really was worth it.
Mine came out with a delicate Strawberry flavour, a lovely light pink colour and just a little sweetness.

And here is the original recipe
************************
Easy Homemade Frozen Yogurt
1 package sugar-free gelatin (4 serving-size), any flavor (I used Hartleys Sugar Free Jelly and nowhere near this amount)
1/2 cup boiling water (I would use just enough to dissolve the crystals - 1/2 cup is way too much)
32 oz. nonfat plain yogurt
1 tsp vanilla extract (I didn't bother with that... cos I didn't see the point )
Combine the boiling water and Jell-o powder in a medium bowl. Stir well, making sure all the gelatin powder dissolves (it has a tendency to clump at the base of the bowl). Allow to cool slightly before stirring in yogurt and extract. Stir until there are no lumps and the gelatin mixture is evenly distributed.
If you have an ice-cream maker, this is the point at which you transfer the mixture and follow your machine's directions. If you're trying it by hand, like me, pour mixture into a freezer-safe bowl and place in the freezer. After 20 minutes, remover bowl from freezer and stir mixture, taking care to scrape the sides of the bowl. Stir until smooth and return bowl to the freezer.
Repeat this stirring process every 25-35 minutes until your frozen yogurt begins to thicken and set. This may take several hours. Be sure not to miss any stirrings as this will cause ice crystals to form in your yogurt. Also, mixing more frequently will result in lighter, creamier yogurt. Serve immediately when yogurt reaches the desired consistency.
