Also known as the "pie plant" because of it's popularity as a filling, rhubarb is often paired with strawberries, which balance out rhubarb's tartness while also add more rosy hues. Here, the two ingredients are also combined with apples to make a delectable jam, with cinnamon lending subtle spice. For a smoother consistency, puree the cooked jam with a hand blender, or just leave it chunkier if that's your preference.
