Wash the rhubarb and cut it into slices about 0.5 cm thick. There’s no need to peel it.
In a bowl, whisk together the milk, eggs, sugar, butter and vanilla extract until combined.
Sift in the plain flour, baking powder and salt, then whisk until smooth.
Add the orange juice and mix well.
Fold in the chopped rhubarb.
Fry the fritters in deep oil, like doughnuts.
Dip a tablespoon into the hot oil, then carefully drop spoonfuls of batter into the oil (1 level tablespoon = 1 fritter).
Fry at 175°C, turning once, until golden brown on both sides.
Transfer to a paper towel to drain excess oil.
Once slightly cooled, dust with icing sugar and serve.
