I always thought I hated rhubarb. Turns out, I'd only ever had it with cooked strawberries and it's the strawberries I hate.
If you know how to make apple crisp, just substitute 1/2 to 3/4 of the apples with rhubarb. You need some apples for structure, though. I usually put down one layer of apples, fill up with rhubarb and add one layer of apples at the top to support the topping. Serve warm with ice cream.
I also found a rhubarb muffin recipe that I really like. I'll have to post it when I get home, though.
And a European style cake with rhubarb and raspberries that is just dusted with some icing sugar, rather than iced. Again, I'll have to find the recipe at home. It was a Weight Watcher's recipe I got from somewhere.
