First I purchased a pack of sliced watermelon from the store. Mine had two large slices in it. I used the fruit from one entire slice of watermelon in my drink. I cut all the watermelon from that one slice off the rind and then chopped it up into squares that were small enough to fit into the muddler. I placed the muddler in the pitcher and filled it with the watermelon cubes.
I then used the muddle stick to crush the watermelon. This allowed the juice to flow into the pitcher.
Once I felt like I had crushed most of the juice from the watermelon, I added the leaves from two large bunches of basil to the muddler. I chose a Thai basil but you could use any variety you like.
I then cut 16 ripe strawberries in half and added those to the muddler. Then I used the muddler stick to crush the strawberries and basil. The watermelon that was in the bottom of the muddler was also being crushed a bit more.
Once I knew there was no more juice that I could get from the fruit and basil, I filled the pitcher with filtered water. You can use tap water or bottled water if you prefer.
Now that the Primula pitcher was filled with water, I set a timer for 7 minutes. I read in the book that leaving the fruit in the water longer than this can result in a bitter taste.
When the timer went off, I pulled the muddler half way out of the pitcher and used the muddle stick to stir the fruit and herb remains around so all the water and juices were released into the pitcher.
Then I filled my pitcher the rest of the way up with water. There is a chill core you can put in the center of the pitcher to keep the drink cold but today mine was not frozen. If you use it, do not fill the pitcher to the top with water as you will need enough room for the chill core.
I poured my basil strawberry watermelon water over cubed ice, topped my glass with a strawberry and inserted a straw. The drink is delicious. If you want to get even fancier, try freezing some seedless watermelon cubes or add some fresh watermelon, strawberries or basil to the glass after it is filled with ice and flavored water.
