This is a recipe for a smooth pudding that can be easily made using only four ingredients and a microwave, without using heavy cream or butter. First, heat sugar and water in the microwave to make caramel, pour it into a heat-resistant container and let it cool and solidify. Next, strain the pudding mixture (egg, sugar, and milk) through a sieve and pour it over the caramel. Place a large container in a makeshift steamer filled with hot water and heat it again in the microwave. Let it cool down to room temperature, then refrigerate until thoroughly chilled, and you'll have a smooth, melt-in-your-mouth pudding. You can also make it deliciously with milk-based beverages such as coffee milk instead of regular milk, so you can enjoy it with your favorite flavor.
