This was really yummy. So much so, that I'm thinking about going back up to the produce market tomorrow to get a few of their $1 watermelons (the ones with the seeds are cheaper) so I can make more fresh watermelon juice!
It's trickier to juice them though when there are seeds, because crushing the seeds would make it bitter. What I did was just cut it up, dust it with a teensy bit of salt, and wait for it to juice itself. After it sat for about an hour, I just crushed the rest with my hands.
A note about the salt ... you only add a small amount, but it benefits in two ways: It helps to break down the fruit's flesh releasing the juice easier, and it also boosts the flavor. The key is to only use a small amount, like when you make cookies, because you only need flavor enhancement, not salty juice.
Watermelon Martini:
2 oz watermelon juice
1 teaspoon of agave nectar
2 oz vodka
Method: Add watermelon juice, agave nectar & vodka to empty shaker. Add ice last and shake immediately - serving instantly after shaking. Watermelon juice tends to bem umm, watery, so by adding ice last keeps it from getting anymore watered down.
Garnishes & Variations: Fresh Mint is my favorite garnish - I just didn't happen to have any on hand today. Also, you can add a splash of any melon-flavored liquor to deepen the flavors, but if you like a fresh flavor, and not fake, I highly recommend you do this in small amounts -- like, half a teaspoon at a time. Grand Marnier is also good in this, but again, just about a half teaspoon per serving.
