Choosing Between Water and Milk: A Guide to Using the Right Liquid in Your Recipes

When to Use Water or Milk in Cooking: A Comprehensive Guide

Water and milk are two essential ingredients found in countless recipes. While both serve as liquid components, it’s important to understand when to use each for the best results. In this comprehensive guide, we’ll explore the unique properties of water and milk in cooking and baking, and discuss the ideal scenarios for using each liquid in various popular foods.

The purpose of milk in cooking and baking

Milk is a versatile ingredient that offers several benefits in the kitchen. It contains lactose, a form of sugar that caramelizes well and helps create a beautiful browning effect in breads, pastries and pie crusts. In addition, milk’s proteins and fats help to stabilize air bubbles, allowing for a fluffier texture in dishes like cappuccinos and baked goods. The fat content in milk also creates a softer texture and richer flavor, while extending the shelf life of baked goods.
It’s important to note that due to its lower fat content, skim milk may not provide the same benefits as whole milk.

The purpose of water in cooking and baking

Water may seem like a simple ingredient, but it can play a critical role in achieving certain culinary results. When heated, water turns to steam, creating airy and chewy textures in foods such as baguettes and pizza crusts. Its slightly acidic nature can enhance yeast activity, making it ideal for sourdough and other bread recipes that require well-fermented dough.
Water also acts as a solvent, dissolving sugar, salt and other soluble ingredients, contributing to sharper and more complex flavor profiles. In addition, water can extract and intensify flavors in dishes, making it useful for reducing sauces, caramelizing onions, and creating concentrated flavor profiles.

Using water and milk in different foods


Milk is typically the liquid of choice in cake recipes because it helps create a tender crumb and a richer flavor profile. However, for cakes with a sharper flavor profile, such as ginger, spice or chocolate cakes, water can be used instead of milk. Water acts as a solvent, bringing out the flavors of the spices or chocolate without adding excessive creaminess.


Water is excellent for making crusty and chewy breads such as pizza dough or garlic bread. It also aids in the fermentation process, making it suitable for long-fermented breads such as sourdough. On the other hand, milk is preferred for softer breads such as rolls or buns, as its fat and lactose content produce a tender loaf with a longer shelf life.


Water is typically used to cook rice, as it preserves the structure of the grains and allows for easy mixing with other ingredients or absorption of sauces. However, in sweet rice dishes such as rice pudding, milk can be substituted for water to create a creamy, custard-like texture. For savory rice dishes, water or broth is recommended to enhance flavor.


Both milk and water should be used sparingly when cooking eggs. Adding milk to stove-top cooking methods, such as scrambling eggs, can result in a rubbery, runny texture. Instead, plain water can be used to make fluffier eggs by taking advantage of the steaming effect. In baking, however, milk combines with eggs to create a custard-like texture that is ideal for dishes like frittatas and quiches.


While water is the traditional choice for cooking pasta, there is an exception for creamy pasta dishes. Boiling pasta in milk can create a creamier texture and infuse the pasta with starchy goodness. This technique is often used in macaroni and cheese recipes, where the milk is strained and combined with a roux to make the cheese sauce.

Corn on the cob

While water is the most common choice for cooking corn on the cob, some Southern cooks prefer to cook it in a mixture of milk and water. Boiling corn in milk can add creaminess to the kernels and enhance their flavor.


Water and milk are versatile ingredients with unique properties that can significantly affect the flavor and texture of various foods. While water is often used for its ability to create steam, dissolve ingredients and intensify flavors, milk adds richness, smoothness and caramelization effects to dishes. By understanding the role of water and milk in cooking and baking, you can make informed choices and create the best possible versions of your favorite recipes.
Remember that while water and milk can sometimes be interchangeable, each liquid has its own unique benefits and effects on the final result. Experimenting with water and milk in different recipes can lead to exciting culinary discoveries. So the next time you’re in the kitchen, don’t hesitate to consider whether water or milk is the ideal choice for your dish, and enjoy the delicious results!


Can I replace milk with water in any recipe?

Technically, you can substitute water for milk in most recipes, but it’s important to consider the impact on flavor and texture. Milk adds richness and unique properties that water cannot replicate, so the results may be different.

When should I substitute milk for water?

Milk is generally preferred in recipes that require a tender crumb, richer flavor or caramelization effects. It works well in cakes, puddings, creamy pasta dishes, and breads that benefit from a softer texture.

Are there times when water is a better choice than milk?

Yes, water is ideal for recipes that require a crunchy or chewy texture, such as crusty breads and pizza dough. It’s also great for dishes where you want a sharper or more complex flavor profile, such as in sourdough bread or reducing sauces.

Can I use skim milk instead of whole milk?

While skim milk can be used as a substitute for whole milk in some recipes, it may not provide the same richness or texture. Whole milk has a higher fat content, which contributes to a softer texture and richer flavor in baked goods.

What about lactose-free or plant-based dairy alternatives?

Lactose-free or plant-based milk alternatives can often be used as a substitute for regular milk. Keep in mind, however, that the specific properties and flavors of these alternatives may differ from those of dairy milk, so results may vary.

Can I use milk instead of water to cook pasta?

While water is the traditional choice for cooking pasta, you can use milk to create a creamier texture in certain creamy pasta dishes. Boiling pasta in milk gives it a rich, starchy flavor. However, this technique is not suitable for all pasta recipes.
