Here's a little tip a friend told me about, and I've been using for months now. If you're trying to stay away from highly processed sugars (as I am) then serve your coffee with HONEY instead of white sugar. Demerera sugar is also a more natural option.
Surprisingly, the honey just tastes smooth and delicious and right in a cup of coffee. At first I was hesitant to try, but give honey a try and you'll be surprised that it's amazingly delicious in coffee.
