*Please note it is more like a dense pudding than jello =)
Step 1: Gather your ingredients and tools
About 9 cups of seedless watermelon chunks (you will need 4 cups once it is puréed)
3 tbsp sugar, maple syrup, agave nectar, or other sweetener (but please don't use the artificial stuff!)
6 tbsp cornstarch
1 tsp vanilla extract
1/3 tsp ground cinnamon
Blender or food processor
Large fine mesh sieve (or cheesecloth)
Rubber heatproof spatula and/or wooden spoon
Optional garnishes -- get creative!
Roughly chopped pistachios, almonds, or other nuts
Grated semisweet chocolate
Chopped up oreo cookies
Step 2: Pur�e the watermelon
Step 3: Strain and simmer
Bring the purée to a simmer over medium heat. Make sure you stir the mixture frequently and use your spatula or spoon to scrape the bottom to prevent scorching.
Step 4: Add more stuff
Then add the sugar to the mixture and mix well.
Once there are no lumps, pour the mixture into the pot with the purée and stir well.
You may now turn off the heat and mix in the cinnamon and vanilla extract.
