Here's a recipe for a milk carton pudding that uses only four ingredients and requires no heavy cream or butter. First, mix sugar and water in a heatproof container and heat in the microwave. Add more water and stir quickly to make caramel. Pour this caramel into the bottom of a flattened milk carton and let it set at room temperature. Next, mix milk and gelatin and let it soften, then melt it in the microwave. In a separate bowl, thoroughly mix eggs and sugar, then add the melted gelatin and mix until smooth. Pour this pudding mixture into the milk carton, straining it as you go. Chill in the refrigerator for at least 3 hours until set. The result is a smooth, wobbly texture with a perfect balance of gentle sweetness and slightly bitter caramel. It's an easy recipe that only requires mixing and chilling, so be sure to try it for your next snack!
