If you don't have ring molds you can either order them online, or do what I did and save soup cans. Remove both ends and use a bottle brush to clean well-my husband used a file to get rid of the sharp bits for me. They work great for this recipe-I use them for individual cakes as well. This recipe calls for Candied Lemon Zest-ingredients and directions will follow mousse instructions. Candied Violets are a nice touch as well. Read through instruction before making this dessert-it's easy to make but takes alot of chill time. Prep time will reflect 1 day.
