What is Evaporated Milk?

Discovering a Pantry Staple

When I first started learning to cook, I kept seeing “evaporated milk” in old family recipes and classic cookbooks. It sounded mysterious, almost scientific, but it turns out this humble ingredient is anything but complicated. In fact, evaporated milk is one of the most useful and underrated items in the pantry.
So, what is evaporated milk? Simply put, it’s milk that has had about 60 percent of its water content removed through a gentle heating process. The result is a concentrated, shelf-stable liquid with a slightly caramelized flavor and creamy texture. It’s not the same as sweetened condensed milk, which has added sugar and a much thicker consistency. Evaporated milk is unsweetened, making it versatile in both sweet and savory recipes.

Why Use Evaporated Milk?

Evaporated milk is used when you want richness without the heaviness of cream. Its slightly toasty flavor and thick texture make it ideal for adding body to sauces, soups, casseroles, and desserts. It also holds up well to heat, so it won’t curdle as easily as regular milk when cooked.
I’ve used it in everything from creamy mashed potatoes and mac and cheese to pumpkin pie and flan. It even works in coffee or tea for a richer, more velvety sip.

How Is Evaporated Milk Made?

The process behind evaporated milk is straightforward but clever. Regular milk is gently heated until the water content evaporates. This not only concentrates the milk solids and thickens the texture but also extends its shelf life. The milk is then canned and sealed, giving it a long storage period without refrigeration.
You can find it in most grocery stores, usually in the baking aisle or near canned goods. It’s an easy solution when you’re out of fresh milk or want to add depth to a dish without resorting to heavy cream.

A Brief History of Evaporated Milk

Evaporated milk was invented in the mid-19th century as a practical solution to the challenges of milk spoilage. Before refrigeration was common, fresh milk had a short shelf life and could be unsafe to drink, especially during long journeys or in warm climates. In 1853, Gail Borden patented the process of preserving milk by removing its water content and sealing it in cans. This innovation proved vital during the American Civil War, as it provided soldiers with a reliable source of dairy. Over time, evaporated milk became a pantry staple in households across the country, appreciated for its convenience, long shelf life, and culinary versatility.

Tips for Using Evaporated Milk

If a recipe calls for regular milk and you’re out, you can substitute evaporated milk by diluting it with an equal amount of water. For example, mix ½ cup evaporated milk with ½ cup water to equal 1 cup of regular milk. But don’t feel like you always need to dilute it, sometimes that extra creaminess is exactly what your recipe needs.
For baking, it’s a key ingredient in classics like pumpkin pie, tres leches cake, and even some custards. In savory dishes, try adding it to creamy pasta sauces, soups, and even scrambled eggs for a luxurious texture.

Storage and Shelf Life

Unopened cans of evaporated milk can last for months in your pantry. Once opened, transfer any leftover milk to an airtight container and refrigerate. Use it within five days. If you notice any change in smell, color, or texture, it’s best to discard it.
