Ah, now here we go. A proper wintery drink featuring my previously-featured blueberry syrup, and equipped with a fantastically nerdy name. I submit that there is none better, at least this time of year.
2 oz scotch (a Speyside blend)
3/4 oz blueberry syrup (up to 1 oz, to taste)
1/4 oz lemon juice
Add 6-7 oz boiling water to a heatproof mug; add the above and stir to combine. Garnish with some ground nutmeg.
