• Fuku in Coral Gables pours a Lychee Sake Slushie ($10) and a non-alcoholic Coco Lime Slushie ($7).

• Cafe La Trova in Little Havana blends its Frozen Mulata ($16) from Diplomatico Mantuano rum, creme de cacao and cafecito syrup.

• Dune Beach Bar at The Ritz-Carlton Key Biscayne serves the Crandon Park Colada and Sunset Margarita, both $22.

South Florida's summer heat has a short list of frozen cocktails worth crossing town for, and three bars are anchoring it this season.

At Fuku on Miracle Mile, the Lychee Sake Slushie pairs sake with lychee for a floral, lightly sweet pour available year-round for $10. Guests who want to skip the alcohol can order the Coco Lime Slushie, a coconut and lime blend priced at $7 and open to all ages.

In Little Havana, Cafe La Trova's Frozen Mulata takes the bar's cafecito syrup and ground coffee and folds them into Diplomatico Mantuano rum, creme de cacao and lime juice. At $16, it reads more like dessert than cocktail, and it is the clearest example on this list of a bar building a frozen drink around what it already does best.

At The Ritz-Carlton Key Biscayne, Dune Beach Bar's oceanfront setting does some of the work, but the drinks hold their own. The Crandon Park Colada mixes Brugal 1888 rum with coconut cream, pineapple and lime, while the Sunset Margarita runs on Codigo 1530 Blanco tequila, lime and strawberry. Both are $22 and served steps from the sand.

None of these are new inventions so much as bars translating what they already do into something built for heat. That is the more useful read for anyone building a summer drinks guide: the best frozen cocktail in a neighborhood is usually the one that tastes most like the bar that made it.
