Also known as "highballs." 

If you decide to throw a last-minute dinner party, you want the planning to be one thing: easy. It doesn't get any simpler than highball cocktails—all you need is one spirit, one mixer, and some ice. In this week's episode of "Things Cooks Know," hosts and Real Simple editors Sarah Humphreys and Sarah Karnasiewicz discuss their favorite two-ingredient recipes, as well as secrets for making your cocktails taste great (hint: the ice actually matters) and the best accessories (Humphreys loves the Tervis Tumbler).
The gin and tonic is a classic, but if you'd like to be more adventurous, try a rum and ginger beer or tequila and grapefruit soda. For more recipes, listen to the full episode below and don't forget to subscribe to the show on iTunes!
