How do you make the mustard sauce from japanese restaurants?

Japanese White Sauce is actually very easy to make.

Sometimes recipes will vary, some people add peanut butter to theirs.

This recipe however, does not! It's very good.

1-1/4 cup

Hellman's mayonnaise *

1/4 cup

water

1 teaspoon

tomato paste

1 tablespoon

melted butter

1/2 teaspoon

garlic powder

1 teaspoon

sugar

1/4 teaspoon

paprika

dash

cayenne pepper

and yes, get Hellman's, it works the best and doesn't have as much as a mayonnaise taste; you DON'T want that.

Using a fork or a whisk, blend all ingredients together thoroughly until well mixed and the sauce is smooth. Refrigerate overnight to allow flavors to blend. Bring to room temperature before serving.

The sauce will NOT taste right if you don't let it sit overnight. And please don't try to substitute ketchup for the tomato paste! The water is needed to bring this to the right consistency.
