What happens when you heat up milk in semolina pudding?

When you heat up milk in semolina pudding, the milk warms and begins to evaporate, which helps dissolve the semolina. The semolina absorbs the liquid and swells, thickening the mixture as it cooks. This process also allows the flavors to meld, resulting in a creamy and smooth texture. Proper heating ensures that the semolina cooks evenly, preventing clumps and achieving the desired consistency.
