My husband is huge rhubarb fan. I hadn't much to do with the stuff until I met him. For his birthday he usually gets some type of rhubarb dessert but I decided to try something new and make this for his breakfast. This recipe is a little bit involved but the results are definitely worth it. Not a rhubarb fan? Don't fret because this could also be made with blueberries, raspberries, sour cherry or any other tangy fruit you can think of. Just adjust the sugar because they would need less sugar then the rhubarb. Next time I think I will try adding strawberries in with the rhubarb....Enjoy!
