11. Make the sage-infused agave nectar: preheat oven to 350°F. Place sage leaves on a baking sheet and heat in the oven for 6-8 minutes. In a nonreactive pan with a lid or glass jar, mix leaves into agave nectar. Cover and let stand 48 hours. Strain out leaves.
22. Fill a mixing glass with ice. Add tequila, mezcal, sage-infused agave nectar, and bitters. Stir until chilled. Add a tall ice cube to a rocks glass (or stack two square ones to nearly reach the top of the glass). Strain cocktail into glass. Express oil from orange twist over the drink and discard. Garnish with sage leaf (ideally, balance it at top of ice.)
