I will add cinnamon to the grounds when brewing.
I've also added orange too. Just "shred" the orange peel and put in with the grounds. Smells really nice!
I went and bought a Keurig coffee maker.
I was wasting so much coffee, just making a pot for myself, that it wasn't cost effective for me to use the big pot with just me drinking it. I was wasting more than I was drinking. With the Keurig, I can make a single cup and there's no more waste. Hubby loves it too for his quick cup to work in the morning.
