Make butter and simple cheese

Shake cream until it turns to butter, and let milk sour and drain into soft cheese that keeps longer than milk.

Fresh milk keeps a day, maybe two. Butter keeps for weeks, cheese even longer, and both fit in a smaller pot than the milk they came from. The trick behind both is the same: take the good part out of the milk and get the water away from it. No special machines — a jar, a cloth, salt, and your arms.

Butter comes from cream, the fatty layer that floats up. Cheese comes from curd, the solid that forms when milk sours. One batch of milk can give you both.

You need

• Fresh milk from a healthy animal — cow, goat, or sheep. Cow milk gives up its cream easily; goat cream rises slowly, so goat milk goes better toward cheese.
• A wide, shallow bowl or pan — cream rises faster with more surface. Cover it with a cloth against dust and flies.
• A jar with a tight lid — your churn. Any size, filled only halfway, so the cream can slosh hard.
• A clean cloth with a fine weave — for draining cheese. Boil it before use.
• Salt — it flavours and preserves both butter and cheese.
• Cold clean water — for washing the butter.
• Boiling water — to scald every bowl, jar, and spoon first. Dirty tools turn milk into poison instead of food.

Steps

1. Set the milk to stand. Pour fresh milk into the shallow bowl, cover, and leave it somewhere cool for 12 to 24 hours. The cream rises to the top as a thick yellow-white layer.
2. Skim the cream off with a spoon into your jar. The milk left underneath is skimmed milk — drink it, cook with it, or turn it into the cheese below.
3. Bring the cream to cool-room warmth — about 13 to 16 °C, cellar-cool. Too cold and churning takes hours; too warm and you get grease instead of butter.
4. Shake. Lid on tight, jar half full, and shake steadily. First it turns to whipped cream. Keep going — after 10 to 30 minutes it suddenly "breaks": yellow grains of butter appear in a thin white liquid called buttermilk. Drink it or bake with it.
5. Wash the butter. Pour off the buttermilk, add cold water, and press and fold the butter with a spoon. Pour off the cloudy water and repeat until it stays clear. Buttermilk left inside makes butter go off fast.
6. Salt and store. Knead in salt — about one flat teaspoon for a lump the size of your fist. Press it into a pot, cover, keep cool. It lasts weeks.
7. Now the cheese: let milk sour. Stand whole or skimmed raw milk, covered, in a warm room (20 to 25 °C) for one to two days, until it sets like soft custard and smells cleanly sour — like yogurt. If the cheese is for anyone pregnant, any small child, or anyone old or already sick, do not sour raw milk for them. Bring the milk to a boil first, cool it to warm, then stir in a spoonful of live yogurt or fresh buttermilk to sour it — same cheese, same days, without the risk. Read the first Watch out before you choose.
8. Warm it gently (optional but better). Set the pot in hot water until the curd reaches hand-hot, about 40 °C. The curd firms and the watery part — the whey — separates clearly.
9. Drain. Pour everything into the boiled cloth, tie the corners, and hang it over a bowl for 6 to 12 hours. Whey drips out; soft white cheese stays in the cloth. Feed the whey to pigs or chickens, or drink it.
10. Salt the cheese — a small pinch worked through per handful, to taste. Eat within a week, kept cool. Salt it harder and press it under a weight for a day and it keeps longer.

Watch out

• Soft raw-milk cheese can carry germs that never smell wrong. Souring beats the spoilers; it does not beat everything. A few of the dangerous germs — listeria worst among them — are perfectly at home in cool, sour, soft cheese, and they give no sour smell, no fizz, no slime, no colour. Your nose is powerless against them, and a healthy-looking animal can carry them without ever being ill. For anyone pregnant, any small child, and anyone old or already sick, make their cheese only from milk brought to a boil first and then soured with live yogurt or buttermilk (step 7). In pregnancy listeria can kill an unborn baby, and that is not a risk anyone can smell their way around. Hard cheese — salted well, pressed, and aged — is safer than fresh soft cheese for everyone. This is the same warning the milk-an-animal guide gives about drinking raw milk; making it into fresh cheese does not lift it.
• Trust your nose, ruthlessly — for the spoilers. Cleanly sour like yogurt is right. Rotten, bitter, fizzy, or any pink, orange, or black patches — throw the whole batch out. When in doubt, out. Just remember what the bullet above says: passing the nose test means the cheese is not rotten, not that it is safe for the people who most need it to be.
• Only raw milk sours safely by itself. Its own good bacteria do the work. Boiled or shop-pasteurised milk has none — left warm, it rots instead of souring. Stir in a spoonful of live yogurt or fresh buttermilk to sour that milk safely.
• Never use milk from a sick animal or from an udder that is hot, hard, or lumpy.
• Butter that won't break after 30 minutes of shaking is almost always too cold. Stand the jar in a bowl of warm water for a few minutes and shake again.
• Unwashed butter goes rancid in days. Wash until the water runs clear — every time.

How it works

Cream is countless tiny fat droplets, each wrapped in a thin skin, floating in water. Shaking smashes the skins so the fat sticks to itself: that lump is butter. Souring is different: friendly bacteria eat the milk sugar and make lactic acid, which clumps the milk protein into curd and holds back most spoilage microbes — that is why sour cheese outlasts sweet milk.

Note that word: most. Souring is a crowd of friendly germs taking the food and turning the milk too sour for the usual rot to get started — it is competition, not killing, and a few of the dangerous ones simply do not mind an acid, cool, damp home. That is the whole reason the milk itself must be sound to begin with, or boiled. Souring makes milk keep. Boiling is what makes it safe.
