For the Fig- and Orange-Infused Scotch:
Pour the Scotch into a sealable glass jar. Add the figs and orange wedges and seal. Let the mixture sit for 2 weeks before serving, tasting throughout to avoid over-infusion.
To Assemble and Serve:
Pour the whisky, Port, lemon juice, lime juice, simple syrup, and egg white into a cocktail shaker and shake vigorously. Add the ice to the shaker and shake again. Strain the cocktail into a chilled martini glass. Sprinkle the bitters over the egg white foam.
