Milk

Taste and Texture

The flavor is generally mild and subtly sweet, with a characteristic dairy nutty aroma. It is a useful base ingredient to connect and soften strong flavors from salt, spices, cheese, and butter. When cold, it tends to be thin, but heating it or using with starch, eggs, or cheese can yield a thicker texture. Boiling milk alone will not thicken to creaminess, so if thickness is needed, use additional thickening agents such as Luna starch.

Main uses

• Used as the basic liquid for béchamel and cream sauces. By gradually adding milk to a roux made from butter and flour, you can create a smooth sauce suitable for pasta, lasagna, and gratins.
• Add to soups containing potatoes, mushrooms, or corn to create a soft base. When the soup is boiling, adding large amounts all at once can cause rapid temperature changes and overflow, so it's easier to handle by reducing heat and adding in batches.
• In batters for pancakes, waffles, muffins, etc., it provides moisture and dairy flavor. If the batter is too stiff, you can add a small amount, but adding too much may cause the batter to spread and undercook inside.
• Stir in with mashed potatoes, scrambled eggs, or oats to soften texture. If you add cold milk all at once, it can lower the temperature of warm dishes and make the texture seem stiff.
• Add to tea, coffee, or cocoa to mellow bitterness or astringency. For delicate-flavored teas, the milk flavor may come forward, so start with a small amount and adjust.

Preparation tips

• Check the smell and state before and after opening. If it smells sour or you see curdling, don't try to hide it in heated dishes; it's better not to use it.
• Let milk for sauces sit at room temperature briefly or warm gently before adding to the pan to reduce the temperature gap when it meets the hot roux. Cold milk can be used, but don’t pour all at once; whisk and add gradually.
• When using acidic ingredients like tomatoes, lemon juice, or vinegar, separate the stage of boiling the milk from adding the acid. If the sauce is already very hot and acidic, it’s better to reduce heat and add the acid in small amounts to minimize curdling.
• If a film forms on the surface during heating, occasionally stir the bottom and edges, and cover with paper if needed. Conversely, if a thin film forms in custards or milk puddings, it is not a problem for recipes where it won’t cause issues.

Cooking characteristics

• When heated slowly, the aroma becomes milder and blends naturally into sauces. This is a good signal for sauces and drinks that are cooked gently and do not require vigorous boiling.
• If boiling strongly continues, the bottom may burn or a skin may form on the surface. If you smell a burnt odor rather than a nutty aroma, move to another pot immediately and do not stir the scorched parts.
• When acidic ingredients like lemon juice, vinegar, wine, or tomato are added, proteins coagulate and grains may appear. They can be used intentionally to make a chunky texture like ricotta, but are not suitable for a smooth cream sauce.
• When heated with starch or flour, starch absorbs water and thickens. At first it may look thin, but the viscosity can rise quickly just before boiling, so it helps to turn off the heat when it is slightly thinner than the desired thickness.

Good combinations

• Butter, flour, and cheese together form the basis for a rich, creamy sauce. If the cheese is too salty, it’s better to adjust seasoning at the end before adding milk.
• Pairs well with mild or naturally sweet vegetables like potatoes, mushrooms, cauliflower, and corn. If the vegetables release a lot of water, it’s easier to handle by reducing some moisture from the vegetables before combining with milk.
• Vanilla, cinnamon, cocoa, and black tea pair with sweet drinks and desserts. Boiling spices for too long can dull the aroma, so remove them once the aroma is sufficient.
• When used with pepper, nutmeg, garlic, or onion, it complements the flavors in savory dishes. If the sharp aroma of garlic or onion remains, it’s better to cook them thoroughly before adding milk.

Points to consider when substituting

• If the goal is the smooth liquid texture of milk in a sauce or soup, unsweetened soy milk or oat beverage can be used. However, products vary in sweetness, thickness, and how much they separate when heated, so start with a small amount to check texture.
• To achieve a richer flavor and thicker texture, you can mix in some cream or combine milk with water. Replacing with only cream can make the sauce too heavy and high in fat.
• In baking, water can substitute for milk, but flavor and creaminess will be reduced. Depending on whether you only need to match moisture in the batter or maintain the nutty flavor and color milk provides, results differ.
• acidic dishes may still separate with plant-based milks. If a smooth texture is essential, it may be better to thicken with starch first or add acidic ingredients in small amounts at the end rather than immediately adding plant-based milks.
