Place the raw pumpkin seeds in a bowl and cover them generously with water. Let them soak for at least two hours to soften. Once softened, drain well and rinse with fresh water. This makes the seeds easier to blend and results in a smoother sauce.
Transfer the soaked and drained pumpkin seeds from Step 1 to a blender. Add the extra-virgin olive oil, small clove of garlic, maple syrup, apple cider vinegar or lemon juice, fresh mint, 1/2 cup water, and a pinch of salt. Add a pinch of ground black pepper if you like a bit of spice. Blend until smooth, adjusting the consistency with more water if needed. Taste the mixture and add more mint or garlic according to your preference. I like to go heavy on the mint for an extra refreshing flavor.
