So I got all the ingredients for this amaro recipe—
—but I had to get liquid gentian root extract instead of gentian root, which was unavailable.
What would be the extract equivalent to the recipe's called-for 1/2 teaspoon of gentian root? The only info on the bottle is that the "botanical preparation ratio" is 1:4, and the ingredients are dried gentian root, distilled water and ethyl alcohol.
My guess is still 1/2 teaspoon, but I'm not sure. And of course I don't want to screw up this ingredient since it's the bittering agent, so too much could render the amaro unpalatable.
