1/2 Syn Strawberry Mousse

What could be better than a sweet, mouth watering, delicious dessert for just half a syn? Not much as far as I’m concerned, and that’s exactly what you get with these simple little individual mousse pots (although you could obviously make one big mousse if you wanted!)…and you get it all in under an hour! 

I’m a big fan of strawberry mousse, it’s creamy, airy and fresh tasting, and this Slimming World friendly version is very very similar to the original. The only difference is that it’s slightly firmer (because of the use of jelly). It’s also quite sweet, so depending on your tastes, you could use less of the jelly powder…which in turn would actually reduce the syns to less than half per portion!

Served in cute little ramekins (these gorgeous heart shaped ones are definitely on my shopping list!) this pudding is perfect whether you’re entertaining or just cooking for one or two, they’ll keep in the fridge for a few days too which is always a bonus.

    Hi tried to make but the jelly starting to set and went all lumpy when I put the yogurts in, please help ?

      Hi Margaret, that's very strange. The jelly should definitely not start setting for a while, did you leave it sitting at all? If you mix straight away there should be no reason why it would go lumpy!
