Ten Cups of Milk, Boiled Down to a Single Lump: A Summer Hearth

Why did people long ago go to the trouble of boiling cow's milk down before they ate it?

Milk today comes in paper cartons and sits chilled on a shelf. You pour it, you drink it, and that is the end of it. Hardly anyone would think of putting it in a pot and boiling it until sunset.

Yet in this country there was once work whose whole purpose was to boil milk down until it set. The result was called so, a solid concentrate of boiled milk. I once hired on to that work and stood before the pot myself. It was only a single summer day's help.

The summer of 1013 (Chōwa 2). In a quarter on the outskirts of the capital where cattle were kept, I found a day's work as a hired hand. The man who put in a word for me was the headman of the household that drew the milk. The pay was a small bag of brown rice and a bowl of gruel at evening. The work was to tend the fire under the hearth and to carry the jars of milk.

Before dawn, the cows were already lowing in the byre. The headman crouched beside a cow, stroking her swollen belly. But hardly any milk came.

"Holding back this morning. What's got into you?"

He slapped the cow on the rump. She shifted her feet. From the side, a boy of ten or so came leading a calf on a rope. Otomaru was his name, a child who seemed the headman's grandson, or near enough. The calf thrust its head under the cow's belly and sucked hard for a while. Then Otomaru seized its tail and hauled it away.

The cow let out a long breath. Under the headman's hands the milk began to fall, chi-chi-chi, into the bottom of a small jar. The headman never so much as glanced at the boy.

Each time a jar filled, I carried it. They were small jars, each one something I could hold in a single arm, and a full one counted as a cup. I laid a large leaf over the mouth and walked the twenty paces or so from the milking place to the hearth shed. One cup, two cups. The jars were still warm as skin, and held against me they dampened my belly through the cloth. This quarter had only three cows, and what they gave in a whole morning came to no more than this, he told me. By the time I had carried the tenth cup, the eastern sky was paling.

The hearth shed was bare, just an earthen floor with one great pot set on it. Into that pot we poured the ten cups of milk. They filled it halfway, white, and a sweet smell rose before any steam had.

The headman drew one damp finger along the inside of the pot, at the very top of the milk. As the milk boiled down, that line would dry white and be left stranded high above it. He would judge the work by the gap. What he wanted, in the end, was only a lump at the bottom of the pot, small enough to rest in both palms. That was so, he said.

"Every summer we owe the office a set number of them. Medicine for the ailing lords. An offering at the turn of the year, too. Our quarter has few cattle. I can't afford to waste these ten cups."

"Keep the fire strong," he said. "The stronger it is, the sooner it sets. I want it finished while there's daylight, and delivered to the office by evening."

I fed the fire with more wood. Dry twigs catch quickly and thick logs last; I felt out the balance in my hands and laid them in at the mouth of the hearth, one after another. The hearth roared. At the rim of the pot the boy was crouching. He had his ear pressed flat against the rim, his eyes shut. Tending the fire was my job. I had no time to humor a child at play.

Then the boy reached out and pulled two logs from the mouth of the hearth.

"Hey."

I picked the logs up and put them back. The boy said nothing. After a while he reached out again. Pulled. I put them back. The third time, he kept his hand on the log and looked straight into my face. I pushed his hand away. The headman had said a strong fire. That was the work I had taken on.

The boy gave up, it seemed, and pressed his ear to the rim of the pot once more.

As the sun climbed, the milk shrank in bulk. White foam swelled and burst. The white that had stood halfway up the pot sank, before I knew it, to a depth of three fingers, and the white line on the pot's wall was left far above. The paddle I stirred with grew heavier by degrees, the shed turned to a steam-room, and sweat ran down my back. Again and again I wiped my face on my sleeve and changed the paddle from one hand to the other. Every time I swept the bottom, a skin of milk clung to the wall of the pot. I peeled it away and stirred again. The bubbles, large at first and popping with a soft poko-poko, grew finer as the milk thickened, and the color moved slowly from white to pale yellow, from yellow to the color of malt syrup. It was dull work, but I felt that the moment I stopped, the bottom would blacken.

Toward noon, the boy lifted the leaf from a jar in a corner of the shed and put his nose to it. It was the leftover milk, drawn the evening before and set aside. He wrinkled his face and pushed the jar toward me. I smelled it. It had a sharp, sour reek. The headman saw this, said only, "Ah, summer," and tipped the whole jar out into the ditch.

I ate my midday gruel standing in front of the pot. Even while I tilted the bowl, I could not stop the paddle. The headman sat in the shade of the yard, rubbing a cow's legs. The calf bleated beside him, begging for milk. The cow's belly, so swollen that morning, had sunk, and her bones showed. The white line on the pot's wall was still a long way off.

One thing I noticed. Even while he was checking that jar with his nose, the boy kept one ear turned toward the pot.

It was when the sun had begun to slant. The contents of the pot had boiled down to the color of malt syrup and dragged a thick thread from the paddle. As the headman had told me, I added one more log to the fire.

Chiri, came a sound.

It came from the bottom of the pot. A tiny sound, like paper being rubbed. Then the back of my nose filled with a burnt smell. I pulled the log out in a hurry and scraped the bottom with the paddle. Too late. What had stuck there came peeling away in black, crackling flakes. A bitter smoke mixed into the sweet smell and filled the shed. When I pushed the door open, the wind drew the smoke outside. I coughed once and stood there, paddle in hand, unable to move for a while.

The boy crouched beside me and, without a word, pointed at the rim of the pot. He had been pressing his ear to it all this time. He had heard the sound before it turned into chiri. The three times I had put the logs back, I had pushed that sound back each time.

The headman looked silently into the pot. He compared the white line on the wall with the bottom, and I could tell from his back that he was counting in his head whether it would still make up the number owed. Then he laid his gnarled hand on the boy's head. He left it there for a long while. I gripped the paddle again and only looked at my own feet.

I did not touch the black at the bottom. With the paddle I gently scooped up only the malt-colored part above it. I moved it onto a wooden tray and set it in the doorway where the wind passed. It was so hot, even as I scooped, that the steam reached my face. As it cooled, the mass slowly tightened. When I pressed it with a finger it pushed back a little. That firm. Ten cups of milk had become a single lump small enough to rest in both palms. When it was cool enough to hold, the headman wrapped it in a cloth of hemp and went out himself, before the sun was down, to hand it to the man from the office.

"The sweet one," the boy called that cloth bundle. After a short pause I answered, "Ah, so, then." The boy nodded, as if to say, that's it, that's it.

As I was leaving, the boy scraped some burnt crumbs from the rim of the pot with his fingertip and laid them in my palm. They were still warm. I put them in my mouth. They were bitter. Far behind the bitterness, a deep sweetness seeped slowly out.

That night, in a corner of the shed, I scrubbed the burnt pot. The black at the bottom would not come off completely, however hard I rubbed. The next morning I left that quarter with my bag of brown rice.

Summer milk left out in the heat will sour in half a day. And yet, from dawn to dusk, in one day's labor, ten cups of it had become a single lump small enough to rest in both palms.

Each time I pour milk from a paper carton today, the heat of that hearth mouth comes back to my cheeks.
