Wash the dill, cut off the ends, and finely chop the whole bunch, including the stems. Give the chopped dill another rough chop with your knife to make sure the stems are nice and fine.
In a saucepan, mix cold water (or vegetable cooking water) with the potato (or corn) starch and the tapioca starch. Bring to a boil, stirring constantly with a whisk until the liquid begins to thicken.
Remove from heat, then stir in the chopped dill, vegan cream, and nutmeg.
Season to taste with salt and pepper.
Notes
* Tapioca starch, when combined with potato or corn starch, contributes to a richer, creamier consistency.
