Frequently asked questions

How many cups does this boozy watermelon lemonade recipe make?

According to the Watermelon Board, each pound of watermelon has almost one cup of juice. So, this recipe has 2.5 cups of watermelon, one cup of lemon, one cup of lime, and one cup of pineapple juice.

The fruits and juice are mixed with 2.5 cups of alcohol or water and a half-cup of syrup. In total, adding in the cucumber and mint would make about 8 to 10 cups. 

What is the difference between agave and simple syrup?

Although agave syrup and simple syrup are both sweeteners, they are made differently. Agave syrup (also known as agave nectar) is made by boiling down the sap from the agave plant. Simple syrup is made by boiling white granulated sugar with water. 

Can I make my own simple syrup at home?

Yes, you can make simple syrup easily at home with no special equipment. All you need is white granulated sugar and water. Combine one-half cup of granulated sugar with 1/2 cup of water in a small saucepan over high heat. 

Stir the mixture while it cooks until it boils and then turns it down to simmer. Let it simmer, stirring frequently until the sugar is completely dissolved. Let the mixture cool completely before pouring it into a clean glass jar. 

What food goes best with this vodka lemonade cocktail?

Almost anything goes great with this lemonade drink but a citrus-based recipe would be sublime. For example, try it with this cranberry orange chicken or slow cooker brown sugar orange ham.

Of course, it also pairs well with a juicy steak or burger. Combine this cocktail with other cocktails and recipes for a tropical boost.

How to store leftovers:

  • Store: You can store your lemonade in the fridge for about five days. It would be best in a covered pitcher or another airtight container. Be sure to remove the fruit slices before storing them. 
  • Freeze: Make boozy watermelon lemonade popsicles by pouring these into popsicle molds. Or you can even pour it into ice cube trays if you prefer. It is a great way to beat the heat on a hot day or to add to other cocktails.

Recipe tips:

  • If you do not have a blender, you can use a food processor or even a chopper or grinder to blend your cubed watermelon and cucumber. If you do not have any of those, you can always mash the fresh watermelon cubes and cucumber by hand with a mortar and pestle or meat tenderizer. 
  • This recipe can be doubled or tripled if you are having a party and need more refreshing cocktails. 
  • If you cannot find any fresh watermelon at the grocery store, you can use bottled watermelon juice in a pinch. It will not taste as fresh, but it will still be a delicious drink. 
  • Beat the heat by pouring this delicious drink into ice cube trays and freezing for several hours. Then you can add them to glasses before you pour in the cocktails. 
  • When having a family picnic or party where there will be kids and those that do not drink, make half boozy and the other half without the alcohol. 
  • If lemons are not in season, you can always use lime wedges for your garnish.  
  • Nutritional information varies depending on the ingredients and amounts you use in your recipe. 
  • You may not get enough water from your watermelon during the off-season because the watermelons are much dryer heading into the winter months.
