In mixing glass with ice, add all ingredients but lemon peel and stir for about 10 seconds. Strain into coupe glass. Express lemon oils from peel by twisting peel over glass, then rub rim of glass with peel. Place peel on top as garnish.
For the Grilled Peach Infused Rum:
Grill peaches on medium to high heat to achieve grill marks on both sides. Once cooled, cut into chunks. Pour rum into large, lidded container and add peaches. Seal container. Let mixture sit for 24 hours to fuse flavors. Strain peaches using cheesecloth. Store liquid in original bottle.
Notes
It’s okay to substitute ingredients with alternative brands of same type and flavor.
