These cups from Leeway Home are not only cute but also perfect for single serving desserts. In her video review, Leah demonstrates how to make a lazy chocolate mousse using these glasses. Instead of the traditional method, she opts for a simpler approach by creating a chocolate whipped cream that still tastes just like regular chocolate mousse. The Leeway Glass set allows for easy layering of the mousse with some strawberry jam, resulting in a delicious and visually appealing dessert. Overall, these glasses offer convenience and style for dessert lovers. However, it's important to note that the video review does not mention any potential drawbacks or limitations of the product.
