Shake all ingredients with ice and strain into a frozen coupe glass.
1. The Gin: I put some Mediterranean-style olives into a glass container, poured in Tanqueray gin to cover + more, put the lid on, and let it "steep" in the 'frig for 3 days. Longer is better.
2. Heavy whipping cream can be substituted for "half & half" to add extra richness & body.
