Begin by adding your silken tofu to a blender and blend until it is smooth and creamy. Next, add in your matzah meal, flax egg, oil, salt, pepper, and dried parsley. Blend until combined. Start with ¾ cup matzah meal and add up to 1 cup to make into a firm, yet slightly sticky, dough. Lastly, add in your fresh dill and blend about 10-15 seconds. At this time, you have your matzah ball dough! Place the bowl of dough in the fridge for 30 minutes to help firm before shaping into balls.
