Love the liquor in tiny quantities, especially good for a sore throat. But that tempting sugar on the bottom!
Well, I figured out how to get it at last.
When the bottle is empty, put it in the microwave on its side, and zap it for one minute. It will be hot, so use a towel to get it out.
Now chip at the bottom with something metal – I use a long bread knife. The sugar will shatter into bits and chunks, and you can pour it out.
The sugar still tastes like the liquor, too. Wonderful stuff.
If the sugar is particularly thick, you may have to mic it a second time to get all of it.
