I didn't realise this kind of work had its own name!
Read the book in one sitting and enjoyed it as a story. There were lots of elements I enjoyed, the alchemy of food, the actual recipes, the magical aspects. Reminded me in lots of ways of 'Chocolat' by Joanne Harris, feeding people and food as the power of nourishment for souls as well as mouths.
The characters I felt were caricatures or stereotypes rather than real people - wicked mother, warrior sister, nurturing Tita, ill-fated and somewhat weak Rosaura.
The combination of the monthly intalments, the inter-weaving of the food and the recipes with the plot were effective.
