I made my own mandarin liqueur and decide this was a good cocktail test (using the ingredients I had). This drink was bright, full, dominant, intense in every positive way possible. However, I couldn't give it a higher rating for a lack of complexity. Very, very solid drink.
Too many flavors going on. do either maple or cinnamon syrups and either the chili liqueur or the peated scotch (10 mls for each) and you've got 4 different good cocktails. It just tries to be too many things at once.
I think there are a lot of ways you could change or improve on this recipe. My first gut reaction was to express and discard a lime peel over the drink which brought out the bright notes in the citrus more. you could also reduce the amount of lime to make the bourbon more pronounced or reduce the simple to make it into more of a sour. Good as is but could definitely be improved on.
