Bring water to a boil in a medium saucepan
Pour in rice, cover, and simmer for 20 minutes
Add hot milk, sugar, and lemon rind, stirring constantly until thickened to oatmeal consistency, about 15-20 minutes. If the consistency still seems slightly runny, it will thicken while cooling. Do not overcook it!
Remove lemon rind and pour mixture onto one large serving plate
Spread flat and allow it to cool
Decorate with cinnamon by pinching some between your fingers and sprinkling a design on top. Tip: Keep your fingers close to the plate to keep the design neat.
Serve at room temperature, but refrigerate to save uneaten portions
