Whip the egg whites and cream of tartar (if using) until the whites are fluffy and stiff. Set aside

Beat the cream cheese and egg yolks until very light. The cream cheese should be completely creamed and smooth.

Add the psyllium husk powder (if using) and salt to the egg yolk mixture.

Fold the whites and yolk mix together gently. Try to keep the whites fluffy and not knock the air out of them. 

Spoon into four circles on a foil line sheet pan and bake in a 350 degree oven for 25 minutes. The rolls will begin to brown slightly.

Remove from the oven and cool before using.
