Rinse and clean rhubarb and strawberries. Peel rhubarb if necessary, then cut into pieces. Cut the large strawberries in half.
Melt currant jelly in a saucepan. Add rhubarb, half of the strawberries, sugar and 1 tbsp red wine. Cover and bring to a simmer.
When rhubarb is soft, stir maizena (cornstarch) with 3 tbsp red wine until smooth, add to fruit form and bring to boil repeatedly. Add the remaining strawberries and leave the grits to cool. Serve with vanilla sauce.
