How much evaporated milk equals 1 cup of milk?

Evaporated milk cannot replace fresh milk in a 1:1 ratio in all recipes due to its higher solids content. To replace 1 cup of milk with evaporated milk, you will need 1/2 cup of evaporated milk and 1/2 cup of water. Alternatively, you can use 3/4 cup of evaporated milk and add just enough water to make up the remaining 1/4 cup of liquid.
