Toasted Pecan Old Fashioned

Japanese whisky infused with toasted pecans, sweetened with Caribbean Mauby syrup — an Old Fashioned with influences from around the world.

What's new here: Toasted-pecan-infused Japanese whisky meets Mauby — a Caribbean syrup made from tree bark that starts sweet and finishes slightly bitter, so every sip shifts as you drink it.

Prep: Toasted-pecan-infused Japanese whisky

  1. Toast a handful of raw pecans on the stovetop or in the oven until fragrant.
  2. Add them to the Japanese whisky and refrigerate for at least 4 hours, preferably 24. The whisky turns noticeably darker.
  3. Strain through a coffee filter twice and keep refrigerated until ready to use. Save the pecans for the pairing.

Prep: Mauby syrup

  1. Gather: 5–8 pieces (about 1/2 oz) mauby bark, 6–10 cups water (divided for boiling and diluting), 1 cinnamon stick, 3–10 whole cloves, 1 star anise (or 1 tsp aniseed or fennel seeds), 1–2 bay leaves, the peel of 1/2–1 orange (fresh or dried), and 3–5 cups brown or cane sugar.
  2. Boil the bark and spices in part of the water, then strain.
  3. Sweeten with the sugar, adjusting to taste — more sugar tames the bitterness.
  4. Dilute with the remaining water to taste. Cool and refrigerate.

Method

  1. Add the infused whisky, Mauby syrup and pecan bitters to a mixing glass with ice and stir.
  2. Strain into a rocks glass over a large tempered ice cube.
  3. Garnish to taste — pictured with a gourmet maraschino cherry, a candied lemon peel and a bourbon-candied orange peel.

Why it works

Toasting the pecans before infusing brings out their nutty, roasted aromas, which the whisky pulls in over a day in the fridge. Mauby is a Caribbean bark-based syrup: it starts sweet and moves to a gentle bitterness — a built-in evolution from the first sip to the last.

Pairing

Re-toast the pecans you strained out of the whisky and add a pinch of flaky salt.

Enjoy!
