Black Currant Candle in Houston??

From your computer on Amazon.

Or do you mean physically purchase in Houston.

I assume you've tried Bed Bath and Beyond's selection of candles.
If no one comes up with a better idea, try La Taste in the Village on a Saturday when Pat (the owner) is working....he might have an idea. I'd also look for European style stores. There is an English store walking distance from La Taste (on Rice Blvd). There is also a potpourri and nicknack store on Times near Kirby in the Village, as well. That place smells terrible, like they have black currant candles...haha Not sure the name, have to look it up.

 

British Aisles, maybe? Or Isles, whatever.
