Wateramount will depend on the moisture content and type of pumpkin seeds
Instructions
Grind the seeds finely in a food processor. (You can use a blender, but you will need to add a bit of the water to get it blending.)
Add the lemon juice, umeboshi paste, and about 1/2 cup of water.
Add more water in small amounts, blending in between, until you get a nice dressing consistency. It may be a bit course, but should be pourable without being too runny. Taste and adjust flavors, adding more lemon or umeboshi paste if desired. The umeboshi paste will add more salt so be mindful.
Set the dressing aside for 10 minutes and check consistency again. You may need to add a bit more water because it will thicken as it sits.
