Separate the yolks from the whites.
In a bowl mix the yolks with the honey until the yolks get whiter.
In a separate bowl, beat the whites until stiff peaks form.
Use a whisker or a spatula to incorporate the whites to the yolk mixture.
Add the sour cream and mix well.
Rinse and drain the blueberries.
Use a hand mixer to puree the fruits.
Slowly add the puree to the other ingredients and mix well to distribute evenly.
Take the mixture to the fridge for at least 2 hours, and then run through an ice cream maker.
If you don't have one, put the mixture in the freezer and stir every 30 minutes so the ice cream will be soft and fluffy.
