In a separate bowl smash the roasted garlic into a paste with the salt.
Cook down the apple juice and vinegar till it is reduced by ½ Cool slightly.
Add the cooked apple juice p to the garlic and mix once more. This should go into refrigerator to get it very cold.
At this point you’ll want to mix the watermelon, onion’s & peppers together being careful not to crush the watermelon.
If you want it hotter mix different peppers and if you want it on the sweeter side add some white sugar to the apple juice and mix till it is all dissolved.
When you are ready to serve put the watermelon mixture into a bowl and spoon the apple juice over it. Mix to incorporate and serve. If you like it more wet add the whole apple juice mixture if not add it by tablespoons till you get it as you like it.
