Two strangers. One recipe. A friendship for the ages.

Creamy risotto alla Milanese. Mussels in a hot, buttery broth. Chicken spiced with cinnamon and cloves. Joan Bergstrom and Imogen Fortier understand the key to a savoured life: delicious food.

Young Joan is just discovering herself as a food writer in bustling Los Angeles, while experienced magazine columnist Imogen is settled in her decades-long marriage on Camano Island outside Seattle. When Joan sends a fan letter to Imogen, alongside a gift of saffron and a recipe, their journey of culinary exploration and life-changing friendship begins.

A long-lost flavour unearths buried memories, a quest to make carne asada opens the doors of a sheltered life, and, as the two women connect through their letters, they build a closeness that sustains them through the unexpected changes in their own worlds.
