I used to think bartenders had it easy. Then, during the COVID-19 lockdown, I took a crack at their craft. Seduced by some sexy cocktail books, I ordered a shaker from Amazon, spent an obscene sum on premium spirits, and invited a few neighbors over for an elevated, socially distanced happy hour.

My first creation was a triumph. Then calamity ensued. I lost track of jigger measurements and bitter drops. Guests got antsy. Ice melted. Citrus wheels drooped. By the time we finally raised our glasses in unison, I concluded I would need to find another way to beat the isolation blues.

J.M. Hirsch, the editorial director of Christopher Kimball’s Milk Street, understands those frustrations. He offers a solution as genius as it is simple in “Freezer Door Cocktails: 75 Cocktails That Are Ready When You Are” (Voracious, $27), his third spirit-focused book.

Here’s how it works: Take a full bottle of booze and pour off just enough to leave room for added ingredients. Cap the bottle, give it a shake, pop it in the freezer and presto! An instant cocktail party awaits.

Recipes range from classic (cosmopolitan, margarita) to fanciful (Caribbean Cruise, Smoked and Sassy) and are organized in chapters according to primary liquor. Hirsch worked out the science to ensure the alcohol levels are sufficient to keep the liquids from turning to ice. Each recipe begins with a lively description and simple taste characteristics ordered by flavor dominance, and ends with a single-serving idea for using the liquor you pour off.

I first mixed the Boulevardier (bitter/strong/sweet), a potent blend of bourbon, Campari and sweet vermouth. Days later I added ice cubes, maraschino cherries and a thirsty neighbor for an impromptu happy hour to kick off the weekend. I may at some point shake up a Love Bug just for myself with the leftover bourbon and Campari, a splash of cognac and dash of angostura bitters.

For anything more complicated than that, I’ll turn to the pros at my favorite drinking spots and thank them for their skills.
