Vinegar is an acid with a low pH. Milk is a complex mixture that has specific protein. When pH of milk drops too low, the casein protein denatures (breaks down) and binds differently to other proteins. The vinegar dropped the pH of the milk too low and this caused the curdling.

What is the process of converting milk into curd?

To convert milk into curd, heat the milk to a lukewarm temperature, add a small amount of curd culture or curd from a previous batch, and let it sit undisturbed in a warm place for 6-8 hours to allow the milk to ferment and curdle. The bacteria in the culture will convert the sugars in the milk into lactic acid, thickening the milk and turning it into curd.

Yes, but you have to first mix the evaporated milk with water (half evaporated milk and half water), then add 1 teaspoon vinegar or lemon juice for each cup of the diluted evaporated milk.
