This recipe for a visually stunning heart-shaped chocolate mousse is perfect for Valentine's Day. A chocolate sponge cake base is encased in chocolate mousse, encasing a sweet and tart mixed berry jelly, and then coated in a vibrant red glaze. The mousse is made with an egg yolk and milk crème anglaise base, resulting in a light and authentic texture. Crushed Lumonde cookies are added for a delightful textural contrast. Decorating with gold leaf, white chocolate shavings, and chocolate pens creates a beautiful, professional-looking finish. It's also an ideal homemade gift for someone special.
