I think using Hayman's make a huge difference. I tried Beefeater and Ransom Old Tom gins, but Hayman's works best here. Update: Chuck Taggart suggests trying Porter's Tropical Old Tom gin. Beefeater will always do in a pinch.
David Lebovitz is okay with Beefeater gin. He uses 1.5 oz gin to 1.5 oz sweet vermouth, 1/2 oz Maraschino liqueur with orange bitters. A bit fruity for my taste, but to each their own.
This one's for you, Kendall! Honey syrup is made with 1:1 honey and hot water. You can shake and strain into an ice filled glass if you prefer. It's great either way.
