Just the name sounds refreshing: aguas frescas.

Fresh waters.

The south-of-the-border specialty mixes fresh fruits and veggies, sometimes with herbs, for a light, chilled beverage.

It’s one of the most popular menu items at the YWCA cafe, 525 N. Bonita Ave., which offers different daily blends for $2 a 16-ounce glass.

“We’re always using what we have on hand and being creative,” says Liane Hernandez, the YWCA’s community life director. “We always put herbs in all our aguas frescas.”

Lately the cafe has been using grapefruit from McClendon’s Select organic farm in Peoria.

“We’re using fruit at the peak of freshness, so we don’t have to use as much sugar,” Hernandez says.

Lime-cucumber-mint is a staff and customer favorite, Hernandez said. “It’s so refreshing and nice.”

Other combos have included strawberry-mint and peach-basil.

“We’re trying to feature what’s in season and what’s available here in Tucson and in our state,” Hernandez adds.

Of course, occasionally, the combos don’t quite work, she says.

“It’s totally trial and error.”
