4 mint leaves

.75 oz simple syrup

1 oz milder scotch

1/2 oz Laphroaig (I don’t have so used 1.5oz Benromach not split base)

1/4 oz Chartreuse

3/4 oz lime

The proportions seem off to me, though it may just be the missing Islay scotch. Less lime, less sugar would work better for me, would recommend - increase the Chartreuse to 1/2 oz, decrease lime to 1/2 oz and just muddle the mint with a pinch of sugar no syrup.
