Recipe Comments & Reviews

Easy and delicious! I planned to make this with strawberries instead of rhubarb, but when I got home from work my boyfriend had eaten half of the strawberries, so I threw in a couple of peaches to compensate. I probably should've also thrown in some more cornstarch, but I didn't, so it's a little goopy in addition to delicious.
