Japanese Salad Dressing

This is quite easy to make salad dressing with quite an interesting flavour, sharp and sweet and salty (from other sauces, I see that ketchup and sugar and white pepper and mustard powder are used to flavour them). If it seems like a lot of salt (which I did, but it didn't taste salty), and you are concerned about your salt intake, you also have to consider the amount of salt in the ketchup, so adjust accordingly. The garlic and onion are sliced, the carrot is shredded, to help in the processing in the food processor. I thought a picture of a salad would be more interesting, here's one we often make.

Japanese Salad Dressing
250 g carrot, shredded
500 g onion, sliced
50 g garlic (2 whole bulbs), sliced
1-1/4 cups distilled white vinegar
4 cups cane sugar
1/2 cup ketchup
1/2 cup salt
1 Tbsp ground white pepper
1 Tbsp yellow mustard powder
5 cups salad oil

Add all ingredients into food processor; process until smooth.
