Hi Dlin, this recipe doesn't use any yogurt. I see what you mean, I wrote "Beat the heavy cream until it reached the thickness of yogurt. Whisk the yogurt and cream until it's smooth and add it to the citrus mixture." That has to be cream cheese instead of yogurt, "whisk cream cheese and whipped cream until it's smooth." Sorry for the mistake! Have a great day, lots of love Véronique
