I think Bman is talking about adding sugar to spirit when making up fancy panty droppers.
I had to read it twice myself.
Bman, I am on a low carb diet at the moment and use “monk fruit with erythritol” sweetener in my almond flour biscotti.
It’s not cheap but the flavour is ok.
I use part of a hermesetas tablets in my coffee, most other types taste like urinal lollies to my tastebuds(don’t ask, I wont tell).
The diabetes thing is stuffed by alcohol anyway, your liver turns the alcohol back to sugar.(not quite correct but near enough).
Personally I don’t like a lot of sugar in those liquors but things like limoncello need something to temper the bitterness.
A lot of the Keto recipes have different sugar replacements in their ingredients.
