Combine the "filling" ingredients.
Make sure that they are all combined very well.
Set aside.
Remove skin from the chicken thighs.
Slice the remaining ½ of the lemon into 4 slices.
Put the chicken into a large pot and top with the lemon slices.
De-stem the grape leaves. Set aside on paper towel covered plate (to allow brine to drain off)
Place the leaves on the work surface, smooth side 'up'(this side is a darker green)
Note: the very veiny side is NOT the side that the stuffing goes on
(it faces out, to allow thorough cooking)
Place the well mixed stuffing on the leaf in a narrow line with a little room remaining at each side of the leaf and at the bottom as well.
After doing so, fold the sides of the leaf inward over the stuffing with a little space in the middle.
Then, take the bottom of the leaf and roll upwards keeping the sides of the leaf tucked in and make sure your leaf is rolled tightly.
You should end up with a cigar-shaped leaf 'package'
Place each rolled grape leaf into the pot forming a layer atop the chicken and sliced lemons
Make a second and third layer (this will depend upon the size or your pot and the number of rolled grape leaves.
Place a plate on top of the leaves, inside the pot
In a bowl, mix together 1 tablespoon cinnamon powder with 2 litres of fresh water
Pour the 'cinnamon water' over the entire mixture, ensuring that the water level is above the plate
Place on stove on high heat to bring all to a boil and then turn the heat down to medium, and cook for 1.5 hours with a lid on the pot
It's all done when you remove one stuffed grape leaf and have a taste.
If the rice inside the leaf is cooked, it's done! If not, replace the lid and cook for another 15 minutes.
