This is the simple Potato Leek Soup I like to make in big batches the day after I roast a chicken. One chicken carcass usually yields about 8 cups of broth which works perfectly for this recipe. I developed it using inspiration from a few online recipes but deliberately took out the usual milk and reduced the butter. I also didn't want too many complicated ingredients to prepare - so kept the spices to a minimum. For safety you will need to use a pressure cooker if you plan to jar and preserve it.
