Remove the whisk from a Hawthorne strainer and add to a mixing pint or shaker. Combine all the ingredients in the mixing pint and shake to emulsify them into a fluffy, cloud-like mixture, about 15 seconds.

Once satisfied with the emulsified texture of the shaker contents, add ice above the liquid level line, and shake again until the cocktail is thoroughly chilled.

Double strain into a chilled glass and garnish with a neatly trimmed orange twist.

*Bonne Maman was used for this recipe, but use a marmalade you like. To double down on the pear note in the bitters, a pear or apple butter would also work.
