Soaking cashews for longer than 10 minutes, up to several hours, can help achieve a creamier texture, especially if you don't have a high-speed blender. Ensure you drain the cashews well before blending. Adjust consistency by adding a tiny splash more soy milk if needed, but be careful not to make it too thin. Taste and adjust salt, acid (apple cider vinegar), and mustard to your preference. Coconut Aminos add a subtle depth but can be omitted or replaced with a tiny pinch of sugar if unavailable. Store in an airtight container in the refrigerator for up to 5-7 days.
