Clean, rinse, and peel the potatoes and carrots.
Cut the potatoes into small pieces about 1 x 2" approx.
Slice the carrots.
In a large pot, boil the potato and carrot pieces together until they are tender enough to smash with a fork.
Drain the potatoes and carrots, retaining 1½ cups of the starchy boiling water.
Add the potatoes, carrots, 1½ cups of boiling water, and all of the rest of the ingredients in to the blender.
Blend on the puree setting until the mixture is very very smooth.
Pour the mixture into a medium sized saucepan.
Bring the mixture to a boil, then reduce heat, stirring constantly.
When the mixture has thickened and pours from the spoon in a sheet (see image above), remove from heat.
Pour into a serving dish and Enjoy!
