Everyone in the family worshiped Grandma Rosa's soup, and no one had ever extracted its secret from her. One Sunday, eight-year-old Leo, who had recently begun to suspect that adults concealed things on purpose, resolved to ask outright.
"Grandma, what's the secret ingredient?"
"It's in the blue jar on the top shelf," she said, without looking up from the onions.
Leo dragged a chair across the tiles, climbed up and lifted the lid with the solemnity of an archaeologist. The jar was empty, apart from a folded slip of paper, which he opened with great care. It bore a single word: "Time."
"That's not an ingredient," he objected.
"Wait and see," said Grandma.
So he waited. He watched her peel the vegetables without hurry, stir the pot in slow figures of eight and hum a song he almost recognized. She asked about school and his friends, and in return she told him about her morning at the market: who had been rude to whom, and what the tomatoes had cost. The soup simmered for three full hours while the window steamed over and the kitchen filled with a smell he would later spend years trying to find again. When at last it was ready, Leo took a spoonful, closed his eyes and considered. "It tastes like the whole afternoon," he said.
Grandma, who had waited all day to hear precisely that, only winked.
