Marmalady's coffee thread prompted me to ask all of you what you flavor your coffee with- or what flavors you like. I grew my rather strong brew in a 4-cup Mellitta maker I got as a premium from Gevalia some time ago; it does a good job. I've been enjoying the flavor I get when I add a dash of ground cardamom to the grounds before brewing. I like the flavor of cinnamon, but I can't seem to get a strong enough flavor from adding ground cinnamon (I use a strong Vietnamese cinnamon from Penzey's). I tried using a piece from a cinnamon stick and putting that in the pot to steep as the coffee drips, but that didn't work either. Any suggestions? I really want to avoid that sludgy residue you get from sprinkling it into a mug of brewed coffee.
