What factors made you read 0 fiction books? *curious* If you can identify them, of course.

Have you actually been applying stuff from it in your own cooking?
Yes! Sometimes it's just about understanding things I had instinctively noticed before, such as why dry lentils are so much slower to cook if you're cooking them in a tomato sauce. I thought it might be something about the higher viscosity, but no, apparently it's the acid. But I've changed my way of doing omelettes after reading the book, for example. I was doing them on too high a temperature and for too long.
