Briefly soak raisins in warm water for 2-3 minutes before adding to plump them up and intensify their sweetness, creating better texture and flavor throughout the pudding.

Assemble the pudding in a bowl by alternating layers of pudding, rice, and cinnamon-raisin mixture rather than mixing all at once to create distinct texture and prevent mushiness.

Mix cinnamon with a pinch of nutmeg, cardamom, or ginger and toast it lightly in a dry pan for 15 seconds before sprinkling to unlock deeper, more complex flavors.

After microwaving the rice, let it cool for 30-45 seconds before combining with pudding to prevent excess heat from making the pudding watery or breaking down the rice grains.

Stir a splash of heavy cream, milk, or Greek yogurt into the vanilla pudding cup before mixing to create a richer, more luxurious mouthfeel and better pudding-to-rice ratio.
