1. Briefly mix the Florida Orange Juice, vinegars, salt, mustard and garlic with an immersion blender, food processor or blender, or with a fork or wire whisk.
2. Slowly add the oil in stream (drop by drop if whisking) until an emulsion forms; or just whisk everything together briefly.
3. Add the remaining oil faster, but still in a stream.
4. Taste to adjust salt and add more oil, vinegar or freshly ground black pepper if needed.
