Take one ripe room-temp watermelon, a little bigger than a human bean's noggin. Cut the fruit into chunks. Take a couple handfulls of fruit chunks at a time and put them into a clean cotton pillow case. Squeeze the dickens out of them over a large bowl to collect the juice... wring 'em out like they owe you money. (It's more difficult to squeeze 'em if they're cold)
Cut 6 lemons in half and juice them as well.
Strain to get seeds/pulp out if necessary, and combine.
In our case, this came out to about 3/4 gallon of pure fruit juice. Funnel it into a jug and chill.
Stir in 1/4 cup sugar - this was actually a little too sweet for me, but might not be sweet enough for you. Next time we will start with 1/8 cup sugar and see how it goes...
Chill. No additional water needed, plenty will come from the melon. Boom, that's it... excellent refreshing watermelon flavor with just a hint of
zing from the lemon juice.
Shake well, add vodka to suit your needs and serve on the rocks...
A cocktail like this is best enjoyed outside in the fresh air, especially after working in the garden for a couple hours.
