In a cocktail shaker or small mixing jar, add 2 tablespoons pumpkin puree, 0.5 tablespoon maple syrup, 0.5 tablespoon fresh lime juice and 3 tablespoons fresh orange juice. Use a small whisk or bar spoon to vigorously stir or shake for 10–15 seconds until the pumpkin is fully incorporated and slightly frothy.

Add rum and bitters

Add 2 tablespoons Goslings Black Seal rum (dark rum) and 2 dashes Angostura bitters to the pumpkin-orange mixture. Stir or briefly shake again (5–8 seconds) to marry flavors.

Prepare glass

Fill a highball or Collins glass with 1 cup of cubed ice (or to the top). If you prefer, you can chill the glass beforehand.

Build the cocktail

Strain the pumpkin-rum mixture over the ice into the prepared glass. Top gently with 4 ounces (about 120 ml) chilled Goslings ginger beer. Stir once gently with a bar spoon to combine, taking care not to overmix so the ginger beer retains effervescence.

Adjust sweetness & flavor

Taste and, if needed, add up to 0.5 tablespoon more maple syrup for sweetness or a squeeze more lime for brightness. Give one gentle stir after adjusting.

Garnish

Thread an orange wheel onto the rim of the glass and lightly dust with a pinch of ground cinnamon. Optionally add a short cinnamon stick as a stirrer.
