Heat oven to 350 degrees. Place rhubarb in ungreased baking dish, 6x10 inch. Sprinkle with salt. Measure sugar, flour and cinnamon into a bowl. Add butter and mix thoroughly until mixture is crumbly. Sprinkle evenly over rhubarb. Bake for 40 to 50 minutes, until topping is golden brown. Serve warm with light cream or ice cream. Randy Rigg
