Ingredient swaps and tricks for homemade lemonade

  • Use frozen lemon juice instead of fresh squeezed juice:
    Mix all the ingredients together and wait a little for the ice cubes to melt. This will be quicker if you use room temperature water.
    You can also let the juice cubes thaw naturally (it happens quite fast, specially if it’s hot) and then use the melted juice just as if it were fresh squeezed juice.
  • Sweetener swaps:
    • You may substitute the liquid stevia for agave syrup, maple syrup, monk fruit in liquid form or honey (some kinds of honey may need you to dissolve them in warm water before mixing it with lemon juice).
    • You can also make this recipe with any other sweetener in powdered form, like Erythriol or xylitol (also with sugar).
      The only difference when using powdered sweetener is that you’ll need some hot water to dissolve it.
      As a dumb rule, heat around 1/4 of the water amount and mix it with the powdered sweetener first. Then add the other ingredients.
  • For a bit of fizz:
    Try switching some of the water for sparkling water.

Watermelon lemonade

Sweet without the need of sweetener and with a very pretty color.
Just substitute half of the water for watermelon juice. For example, for a serving you’ll need:
3 Tbsp. lemon juice + 1/2 cup water + 1/2 cup watermelon juice

Can I make lemonade with Splenda?

Yes. Simply use the equivalent amount of Splenda for 2 Tablespoons sugar per cup. If you’re looking for a sugar-free lemonade recipe, liquid Splenda is a good option.

How long does sugar-free lemonade last in the fridge?

Homemade lemonade is always best enjoyed fresh, but sugar-free lemonade will last for about 2-3 days in the fridge (1-2 days if you add sparkling water).

Can I make homemade lemonade with lemon concentrate?

Yes. Fresh squeezed fruit has a better flavor than concentrate, but if you’re in a pinch or don’t have lemons on hand, lemon juice from concentrate will work. Simply use the equivalent amount of bottled lemon juice for the fresh squeezed lemons called for in this recipe (around 3 Tablespoons per cup).

    Such an easy and great recipe!
    I also loved the idea of preparing lemonade from lemon juice ice cubes.
    I have never used liquid stevia till now: I only use stevia powder and as the quantity I use is so little, I can stir it well.
    But do you think it’s better liquid type?

    1. Thank you so much for your kind comment.
      Stevia changes quite a lot from brand to brand, so if you already have one you like, I wouldn’t change it.
      I personally like liquid stevia to prepare drinks because it’s more convenient.
      But liquid stevia (or at least the one I have) must be stored in the fridge after opening and the shelf life is shorter than for powder stevia. That’s a thing to consider.
