Sift together the flour, xanthan gum, baking powder and cinnamon.

In a separate bowl, mix together the egg yolk, oil, pear puree and pear juice.

Mix in the flour mixture and combine together well.

Whisk together the 2 egg whites, until they are stiff and fold them into the batter.

Spoon the mixture into 12 muffin cases.
