This is a simple, refreshing summertime drink. You can vary the amounts of salt, sugar and lime juice to suit your tastes. Start small, and go from there. You can also use honey instead of sugar. Agave syrup is a good choice, too.
Put the cucumbers, salt, sugar and lime juice in the blender. Cover with 6 cups of water.
Blend until totally smooth. Set a fine-meshed strainer over a bowl and push the liquid through it. Taste the liquid and add more salt, sugar or lime juice to taste. Serve over ice.
Notes
You can add more lime, salt or sugar, but this will get you started. Remember to taste the cucumber skin and peel it if it's bitter.
Variations
You can add an herb like mint, cilantro, lemon verbena, hoja santa, or some other sweet herb. Pitiona is a great option.
Grated ginger and lemongrass give this a Southeast Asian flair.
