"Ramune" is an old word for lemonade, and "Curry Lemonade" or "Curry Soda" is exactly what it sounds like. Ritsuko came home one day recently with this bottle of curry-flavoured soda. The drinks market is fiercely competitive in Japan, and companies release a constant stream of odd drinks. They're usually novelty items, on sale for a limited time and often in a limited area. If something turns out to be popular it may get wider distribution, and once in a while a new drink may actually become a permanent country-wide fixture.
Curry Lemonade is not such a product. We speculated about the taste before opening it. I thought it'd have a neutral sweet flavour but a curry-like smell and I was close. The smell is spicy, thick and hot; similar to Garam Masala, the spicy Indian spice mix. it prepares you for something peppery and hot, but the flavour is mild and sweet, with only a hint of (I think) cardamom. Me, I'd have preferred a slightly more adult taste, with more spice and less sugar.
It's not bad all but it is a novelty drink. Do try it once, but once or twice is enough.
