Yum! I would like a little more mint in mine so I will make another batch of syrup with triple the mint. I think the ratio of espresso to milk is spot on. I made mine sugar free with stevia (instead of sugar) and sugar free hot cocoa (but note that you will use only 1 T of sugar free cocoa instead of 3T regular cocoa due to the decreased volume)! UPDATE: I made this again today with the leftover syrup. If you follow the instructions, you will end up with almost 2.5 cups of liquid which we find is enough for 2 people - so if you are making this for just 1 person, make sure you have a mighty big mug!!! (Most mugs only accommodate 8oz or 12oz).
