A while ago, I was in Kolkata, India, where I had a delicious yogurt drink with lemon. However, I was told that the lemon used to make this drink was a special kind of lemon that was not very juicy but more aromatic. Indeed, the yogurt drink smelled like lemongrass. However, I have forgotten the name of this lemon. Does anyone have an idea of what lemon I am referring to? Thanks in advance.
