Next juice your lemons! You will need 1 cup of lemon juice. Now of course you could go out to the store and BUY lemon juice in the bottle - but that's cheating and it's oh so much better if you do it yourself!!!
Now onto the watermelon... And yes - it was as ripe and juicy as this picture... Please oh please find a watermelon that is THIS good. YUM!!!! It'll be worth it as it'll have much more flavor!! =)
You will need 8 cups of cubed watermelon. Blend 4 cups of watermelon at a time. 4 cups cubed watermelon should equal about 2 cups of juice.
Please don't forget this step unless you like A LOT of pulp in your drinks!!! ;-) You will need to strain the watermelon juice through a pretty fine sieve. Now here is the trick -- strain it TWICE. You will get sooooo much more pulp out. The first time we did it was okay - but we had to drink it through our teeth.. lol straining it twice does the trick!!! Don't leave this step out =)
Combine in a gallon pitcher the sugar syrup mixture that you boiled, 6 cups of cold water, the lemon juice, and watermelon juice that you strained.
