The Good Doctor

I don't drink highballs very often but I saw this recipe and gave it a shot. It's a little sweet. Next time I'll up the rye and use less amaro. It has good flavor. I used Rababaro Zucca for the amaro and it's rhubarb flavors work well with the Dr. Pepper.

1.5 oz Amaro
1.5 oz Rye whiskey
6 oz Dr Pepper
Orange slice, for garnish

Fill a glass with ice. Combine Amaro and rye, and top with Dr Pepper; squeeze orange slice into mixture, and drop the slice into the glass as garnish.
