Holy junk, have I stumbled upon something yummy:

Watermelon Lemonade

1	cup lemon juice
1	cup superfine sugar
4 1/2	cups water
3	cups chopped seeded watermelons
2	tablespoons light corn syrup

1. In a blender, puree the watermelon with the corn syrup.
2. Strain to remove any bits of seed that remain.
3. Combine the lemon juice and sugar in a large pitcher.
4. Stir until the sugar is completely dissolved.
5. Add the puree along with the water.
6. Serve over ice in tall glass.

I bought seedless watermelon at Costco and it was too ripe, kind of like biting into some Memoryfoam- so I looked for drinks on Recipiezaar (my new fave site). One of the raves about it said that 'it is the nectar of the gods', so I thought I would try it. So yummy!
