It isn’t just her notes to which I owe a debt. She also had old cookbooks that she heavily annotated. Some of these books are now well over a century old and reflect a long bygone era. They are early attempts to codify Raj cuisine, and are pitched at the “mistress of the house”. Just remarkable reading.
Interestingly, Google books and the Gutenberg project have some of these books available. Look at Wyvern’s “Culinary Jottings for Madras”, which is one of the more famous books of this era.
