while I like my spoon to stand up in my coffee, I think a 4 to 1 ratio is good for medium. did you buy your own chicory to add to some coffee? I love to mix my own, but like it a bit heavier on the chicory. cheers!
not knowing what you grew up with and what your tastes are, all you can do is make a pot and test it out. I actually buy coffee w/chicory and still add some more. I also like to make cafe au lait w/stronger coffee.
