Kewpie Mayonnaise

I love Kewpie mayonnaise, but can't find it in my hometown. I've tried my best to duplicate it, and this is what I've come up with.

• Ready In: 5 mins
• Yields: 1 cup

Ingredients

• 2  egg yolks, at room temperature
• 1 1⁄4 cups canola oil
• 1  teaspoon salt
• 1⁄2 teaspoon sugar
• 2 -3  tablespoons seasoned rice vinegar

• Correction

•  use two egg yolks instead of one egg

Directions

1. Crack egg into the bowl of a food processor.
2. Add salt and sugar, and process until well combined.
3. With the motor running, add the oil in a slow, steady stream until all is incorporated.
4. With the machine running, add the rice vinegar.
5. Cover, and refrigerate for at least an hour, before ready to use.
