Raw milk is one of the most versatile ingredients you can bring into your kitchen. Because it hasn’t been homogenized or heat-treated, it behaves differently from store-bought milk: the cream separates naturally, it cultures easily into fermented foods, and it can sour into a usable ingredient rather than simply spoiling. Here’s how to make the most of it.
Skim the Cream
The first thing most people do with raw milk is separate the cream. Because raw milk isn’t homogenized, the fat globules are left intact, which means the cream floats to the top on its own. Pour your milk into a wide-mouth container, cover it, and refrigerate for at least 24 hours. Within one to three days, you’ll see a visible cream line form.
Use a ladle or turkey baster to carefully lift the cream off the top without dipping below that line. Every pass of the ladle agitates the milk underneath and dilutes your cream, so work with a steady hand. If the milk is cold, you’ll get heavy cream suitable for whipping. If you separate it while the milk is still warm (around 101°F, roughly the temperature it leaves the cow), you’ll get an extremely thick, spoonable cream similar to what Europeans call “double cream.”
The cream works for butter, whipped cream, ice cream bases, or simply pouring over fruit. The skim milk left behind is excellent for baking, smoothies, or any recipe where you want the dairy flavor without the richness.
Make Kefir
Kefir is one of the simplest fermented foods you can make, and raw milk takes to it naturally. You’ll need kefir grains, which are small, rubbery clusters of bacteria and yeast you can buy online or get from someone who already cultures kefir (the grains multiply over time).
Pour one pint of raw milk over your starter grains in a glass jar. Cover the jar with a cloth or towel to keep dust out while letting oxygen in, then leave it at room temperature for about 24 hours. The result is a tangy, drinkable fermented milk loaded with beneficial bacteria. Once your grains have grown to about four tablespoons, you can culture a full quart per day. At half a cup of grains, they’ll handle up to half a gallon daily. Strain the grains out, refrigerate your kefir, and start the next batch.
Culture Yogurt
Making yogurt from raw milk requires a few more steps than kefir, but the results are worth it. Heat the milk slowly in a stainless steel pot to 180°F and hold it there for 30 minutes. A skin will form on the surface as you go; skim it off or eat it as a snack. Then cool the milk back down to between 68°F and 78°F before stirring in your yogurt starter culture.
Let the mixture ferment at room temperature for 12 to 18 hours. You’ll know it’s done when the yogurt has gelled and pulls away from the sides of the container. Transfer it to the refrigerator and let it rest for at least six hours to develop flavor and a thicker consistency. If you’re activating a freeze-dried culture for the first time, expect the initial batch to take up to 48 hours, and you may need to repeat the process up to three times before the cultures are vigorous enough to ferment properly in raw milk.
Try Simple Soft Cheese
A basic rennet-set fresh cheese is a great starting project for anyone curious about cheesemaking. Heat your raw milk over low heat until it reaches 90°F. Stir in a quarter teaspoon of liquid rennet (animal or vegetable) per gallon of milk, distributing it evenly. Then leave the pot undisturbed in a warm spot for about an hour. The milk will gel into a large, soft curd.
Cut the curd into roughly one-inch squares, let it rest for a few minutes, then gently ladle the curds into a cheesecloth-lined colander to drain. What you’re left with is a mild, creamy fresh cheese similar to queso fresco or paneer. Salt it lightly and use it in salads, tacos, or pasta. The leftover whey works well in bread dough or smoothies.
Let It Sour Into Clabber
One of the oldest uses for raw milk is simply letting it sour naturally into clabber, a thickened, acidic milk that was a staple leavening agent before commercial baking powder existed. Leave unused raw milk on the counter at room temperature for two to five days, depending on the warmth of your kitchen. The milk will thicken and separate slightly as naturally occurring bacteria convert the lactose into lactic acid.
Properly clabbered raw milk should smell pleasantly sour, not rotten. If it makes you recoil when you open the lid, discard it. This distinction only applies to raw milk. Pasteurized milk that sours has lost the protective bacterial cultures that keep harmful organisms in check, so it should always be thrown away rather than repurposed.
Clabber works as a direct substitute for buttermilk, yogurt, or sour cream in recipes. Use it in pancake and waffle batter, chocolate cake, banana bread, muffins, biscuits, yeast rolls, casseroles, or soups. The acidity reacts with baking soda to produce lift, giving you fluffy quick breads and tender cakes. Store clabber in the refrigerator between uses. You can also strain the curds through cheesecloth to make a simple clabber cheese.
Safe Storage and Handling
Raw milk is more perishable than pasteurized milk and needs careful handling. Keep it refrigerated at 40°F or below at all times. Bacteria multiply rapidly in the “danger zone” between 40°F and 140°F, so never leave raw milk out for more than two hours at room temperature, or more than one hour if the ambient temperature is above 90°F (think summer picnics or hot cars).
Store raw milk in glass containers whenever possible, and sanitize them before each use. The simplest approach is boiling: submerge disassembled jars and lids in water and boil for five minutes. Alternatively, soak them for at least two minutes in a bleach solution of two teaspoons of unscented bleach per gallon of water. Don’t rinse after sanitizing, as tap water can reintroduce bacteria onto clean surfaces. Let them air dry on a clean towel.
Know the Risks
Raw milk can carry harmful bacteria, including Campylobacter, Salmonella, E. coli, Listeria, and Brucella. These organisms are killed by pasteurization but survive in unpasteurized milk, and they can cause serious illness, particularly in young children, pregnant women, older adults, and anyone with a weakened immune system.
One claim you’ll encounter often is that raw milk is easier to digest for people with lactose intolerance because it retains natural enzymes and bacteria that break down lactose. A controlled pilot study published in the Annals of Family Medicine tested this directly and found that raw milk did not reduce lactose malabsorption or intolerance symptoms compared with pasteurized milk. The researchers noted that while unpasteurized yogurt does seem to help with lactose digestion (likely because its thickness slows transit through the gut, giving bacteria more time to work), the same benefit didn’t extend to liquid raw milk.
If you choose to use raw milk, sourcing matters. Buy from farms that test their herds regularly, practice clean milking protocols, and keep their milk cold from the moment it leaves the animal. Many states regulate raw milk sales, and some prohibit them entirely, so check your local laws before purchasing.
