Thanks for this. I took some time and read through the preview. One thing I noticed is she used 40% ultrapasturized cream which I don't think I have ever seen here. She says if you use this, there is no need to temper the yolks. She does say you can up the cream% by adding butter. So i guess I can use the cream i get here, add butter and temper the mixture. Our whipping cream is 35% BF. Any thoughts?
