Slice Rhubarb into relatively small slices. Add the sugar and orange juice (Or Port) in a small pan and stir gently to dissolve the sugar. Bring to a low simmer and cook a couple minutes until the rhubarb softens. Try not to stir much as it softens to avoid breaking up the rhubarb. You can use Frozen

Once cooked - set aside and allow to cool

Put the cream and yogurt in a bowl and beat until relatively stiff peaks form

Set aside a couple pieces of rhubarb to decorate the top of the glasses and fold the rest into the cream mixture. Divide the mixture between two glasses and top with the reserved rhubarb. Chill until ready to serve. I add a pc of Mint :)
