My changes address the questions or issues raised in the above three Comments. I used 1.5 oz El Tesoro anejo tequila, 1 oz Cynar, and 1 oz Dolin sweet vermouth. Also used Bitternens Hopped Grapefruit bitters and Angostura Orange bitters. And the lemon peel, of course. Great drink! Very smooth, but a tad too sweet for my taste. Perhaps 0.75 oz Cynar for less sweetness? Rated 4.5 as I made it. Enjoy!
