Lemon & white chocolate truffle in Pastry & Baking Posted November 17, 2020 On 10/26/2020 at 12:30 PM, Jim D. said: Are you using "truffle" in the true sense of a ganache or other filling rolled into a ball (or other shape) then dipped in chocolate or something such as cocoa powder, coconut, or nuts--or in the wider sense of a bonbon filled with ganache or other filling then sealed with chocolate? If you are making a ganache and have Ewald Notter's book, his recipe for lemon is very lemony, and lastingly so. He calls for both juice and zest. But his is too fluid to roll into a ball. If you need it to be firm enough to roll into a ball, then I think, as Kerry has already said, you can add (more) lemon zest and lemon oil. For lemon oil, I strongly recommend Boyajian. Some experts, such as Kirsten Tibballs, caution against leaving zest in a ganache, warning of textural changes over time, but I have never found this to be true. Which of Ewald Notter's books are you speaking of? The Art of the Chocolatier? or Chocolates & Confections?
