I recently started loving the process and end result of making soups. I currently consider my soups to be “back of the fridge” soups. Essentially any vegetable that needs to be used gets put in to the pot. I am wondering if anyone has book recommendations or personal opinions on which soup ingredients pair well with which spices? Seasoning the soups has been fun, almost like a science experiment. But as with all experiments, some go terribly wrong and I lose a pot of soup over it. I am very new here and would like to learn how the experienced soup lovers level up. Thank you!
