Greek Yogurt is such a good substitute especially for creamy desserts like pana cotta! This recipe is great for anyone who wants to be a little more healthy or is watching what they eat. The recipe calls for Greek Yogurt, but does not specify what percentage of fat. If you don't want a high fat dessert, then just use 0%, but it will likely taste better if you use 5%. Good luck! https://entertainingwithbeth.com/greek-yogurt-panna-cotta/
