Frosty, cooling drinks like juleps and cobblers were trending in early 1800s America, their popularity driven by the recent year-round availability of ice. Blocks of it were cut from ponds and lakes in Massachusetts and Maine in the winters, then sold locally or exported abroad on ships specially insulated to keep as much of it solid as possible. When the cold cocktail trend caught on in the United Kingdom, thanks in part to books like Charlie Paul’s “Recipes of American and other Iced Drinks,” London ice delivery men wore uniforms with eagle buttons to reinforce the product’s U.S. provenance.
