Add the nectarine cubes to a blender or food processor and blend until completely pureed. I have a vitamix and it purees it completely, but if your blender leaves some chunks, you can add a little water to the blender, blend it and then strain out the juice. Combine the nectarine puree, vinegar, hoey, garlic, salt and pepper in a large bowl and whisk together. Stream in the olive oil while constantly whisking until the dressing comes together. Store in the fridge for up to one week.
