Preheat oven to 190 degrees C. Grease muffin tin or line with paper patty cups.
In a medium bowl stir together egg, oil, orange juice and zest. In a separate bowl, combine flour, sugar, baking powder, bicarb soda and salt. Stir egg mixture into flour mixture, just until moistened. Fold in chopped rhubarb.
Bake in preheated oven for 20 to 30 minutes, until a skewer inserted into a muffin comes out clean.

Very good basic recipe. I added chopped walnuts, increased the orange rind to a tablespoon and like other reviewers sprinkled them with brown sugar. If eating the same day as making I would use melted butter in place of the oil (better flavour). - 29 Sep 2008
They're nice!!! True, they aren't terribly sweet but sometimes that's o.k. too. Be creative; add brown sugar to the tops before baking and/or reduce the amount of rhubarb or add some chopped apple or strawberries or banana to the rhubarb! I will make these again. Oh, they also rose beautifully and the aroma in the house is heavenly. - 29 Sep 2008
