- Mix the salt and baking soda with water until dissolved. Some people heat the water to get it all perfectly dissolved; I just shake it up and call it good enough. Add the lemon juice, lime juice and sweetener and shake well to combine. You may find that the honey is difficult to mix in; just keep trying, try a long knife to stir, and shake well before serving. Store refrigerated for up to a week.
I squeeze lime juice in bulk and freeze tablespoon-sized servings, then just add one cube to this mixture.
*The larger amount of salt is closer to the WHO guidelines, but the 1/2 teaspoon is what tastes right. So adjust to taste and your level of need for electrolyte replacement versus just a yummy drink.
**Another flavoring option is to use 1/2 c. orange juice and 2 Tbs. lemon juice in place of the lemon/lime mixture.
