Allende's method is strict and a little bit ceremonial. She writes alone, in silence, for long stretches, and she doesn't plan the story in advance. The first draft comes out in one long push before she shows it to anyone.

The Direct Answer
In silence and solitude, ten to twelve hours a day, on a computer, with no outline.
She lights a candle to begin and follows her instinct through the first draft, per her official interviews.

Silence, Solitude, and a Candle

The workday starts early and quiet. Allende lights candles for the spirits and the muses, keeps fresh flowers and incense nearby, and takes a few minutes to settle before she begins. Then she's alone with the page. She doesn't take calls, doesn't chat, doesn't break the quiet. That silence is the point. It's how she hears the story.

I spend ten, twelve hours a day alone in a room writing. I don't talk to anybody. I don't answer the telephone.

No Outline, No Peeking

Allende writes straight onto the computer without an outline, following instinct rather than a map. She has said she doesn't talk about the book while it's in progress and won't read parts of it aloud until the first draft exists. The early weeks are often slow and feel wasted, and she pushes through them anyway. She keeps showing up until the story starts to move.

She works this way until the whole first draft is done, then eases off and starts the long stretch of revision. She has talked about correcting to the point of exhaustion before she'll finally let a book go.

The January 8 start date sits at the front of all this. See the full Isabel Allende writing routine for how the pieces fit together.
