How can I imitate a coffee yoghurt? I used to enjoy coffee yoghurts and eat them often... However, where I'm currently living coffee-flavored yoghurts are unavailable. I've tried to sort of make my own by adding a bit of instant coffee mix and some sugar to plain yoghurt, but it doesn't taste nearly the same. Are there any other ingredients I can try adding? Has anyone ever tried this?
"Instant" coffee typically is disolved in hot water, so I'd think that just stirring it into a cold product would be less than ideal.

You might try making a coffee syrup (as you're adding sugar anyway) or try steeping the instant coffee in hot milk or water first, cool it down, then mixing that into the yoghurt.
