Entitled, "Krua Sa Pathum" (The Kitchen of Sa Pathum Palace), it contains colourful photographs of HRH the Princess Mother and HRH Princess Maha Chakri Sirindhorn, while cooking in the palace  plus their own handwritten instructions for 12 cooking recipes. 

Two recipes written in English by the late the Princess Mother are 'Boston Baked Beans' and 'Boston Brown Bread' - both favourites of His Majesty the King as the Princess Mother cooked for the King when he was young.

The other 10 recipes are written by HRH the Princess in Thai and English.

The menus include 'Ya Pok Hua Dek'  Spinach Cheese Toast, 'Massaya Kasian Samut'  Baked snakehead fish soaked in milk and butter, 'Kung Bor Morakot'  Freshwater giant prawn on top of seaweed grilled on hot granite rock  and 'Pad Prik On'  Prawn and pork stirfried in Chinese tea seed oil with shrimp paste.

The diary is published by the Queen Savang Vadhana Foundation founded by HRH the Princess and costs Bt299. It will be launched today at the National Book Fair at the Queen Sirikit National Convention Centre and will soon be available in bookstores across the country.

Proceeds will go towards the construction of a museum dedicated to Queen Savang Vadhana at the queen's former residence, Tamnak Yai, in Sa Pathum Palace.

It was HRH Princess Sirindhorn who initiated the idea that Tamnak Yai be turned into a museum with the aim of making it a culturalheritage site and a place to teach the younger generation about Thai history and the life of the late queen.

The queen was the Princess's greatgrandmother.

Queen Savang Vadhana, whose life spanned six reigns, including that of HM the King, was the daughter of King Mongkut (Rama IV) and was Queen Sri Savarindhira to King Rama V.

Tamnak Yai in Sa Pathum Palace was the residence of the Princess Mother and HRH Princess Maha Chakri Sirindhorn currently resides there.
