The cantarito is a regional specialty from jalisco, mexico, named for cntaro, the small clay vessel in which it is traditionally served. Essentially a paloma dressed up with more fresh juice, the cantarito is refreshing and bright, and easy to make. Jarritos is the typical choice for grapefruit soda, but many cantinas and roadside stalls in mexico have switched to less-sweet squirt. Weve seen recipes that call for simple syrup or agave nectar, but we think that a healthy pour of orange juice provides more than enough sweetness.
