Whilst the review does mention the Peychaud's bitters (as another comment of yours promises!), I think you forgot to update the recipe too. Going to go and make one of these now...
On the edge of great/good-ness?... Used 99 Bananas again... Begged for sweetness; added 1/4 oz 1:1 turbinado syrup. Got it closer... Wild Turkey was nice in this, but does the overall expression need an overproof whiskey to make it excel?
