Lemon Berry Cubes are super easy to make and are the best way to plan ahead to enjoy some delicious berry lemonade or any other citrus berry cocktail.
* If you don't like seeds, you will need to either use fruit that has no or very tiny seeds (like blueberries and strawberries), or you will need to thaw your fruit and press it through a fine mesh sieve once blended.
* Also, this makes a very tart lemonade when blended with water because of the berries. I intentionally left it tart in case you want to mix it with a sweet soda. If you intend on just blending these cubes with water, you may want to add more simple syrup.
