I experimented tonight with a small batch of walnut-infused bourbon; this was one of the more successful results, a variation on the classic Bee's Knees. It's actually closer to the formula of a Gold Rush, but that's a more modern drink.
1 1/2 oz walnut-infused bourbon
3/4 oz honey syrup
1/2 oz lemon juice
1 small dash Angostura bitters
Shake and strain into a cocktail glass. Garnish with a lemon twist, if you insist; or maybe a walnut half dropped into the bottom of the glass.
I'd like to try this as a toddy too - but I'll need more walnut bourbon for that.
