I would like to try recipes from Urvashi Pitre's Indian Instant Pot Cookbook: Traditional Indian Dishes Made Easy and Fast. However, buying the original Instant Pot pressure cooker does not seem to be straightforward or convenient for customers in Europe (outside Britain).
Has anybody tried these recipes with a pressure cooker that is more readily available in Europe (Germany)? I'm still used to old-fashioned models without any electronic controls, so I am wondering what could be a good alternative option to acquire.
UPDATE Here is a sample recipe from the book (linked from this article in The New Yorker).
