Preheat the oven at 400F/200C. 

In a medium sized bowl, combine walnuts and cinnamon.

Cut a thin slice from the bottom of apples so that they are flat and can stand stable. Cut their top off and scoop the center of each using a tablespoon. It is easy to do it by twisting the spoon inside. Make sure you remove all the seeds. 

Scoop a bit more from the ‘walls’ to make enough room for the filling. Don’t throw the scooped parts away, we are going to use them in the filling. Put aside.

Chope the scooped apple pieces and throw them into the filling, stir well.

Stuff the apples with the filling and place them in a baking pan.

Top each with a piece of butter.

Peel a beet, poke a knife into it randomly so that it gives its lovely color. Place it in the pan and then pour water over it. Then bake the apples for 30 minutes or until the apples are tender. Remove the pan from the oven, transfer the apples on a plate.

If the water left is not too little, pour about ½ cup hot water in the pan. Add 2 tablespoon of honey or maple syrup in the pan, give it a good stir and put it back in the oven. Cook it for 5 minutes or until it gets slightly thick. 

Remove the beet and transfer the syrup in a bowl and let it cool.

Serve the apples with a drizzle of beet syrup.
