• 3 T Worcestershire sauce
• 3 T Japanese soy sauce (buy it on Amazon)
• 2 T mirin (I prefer to use a non-alcoholic variation—buy it on Amazon)
• 1 T brown sugar
• 1 T rice vinegar (buy it on Amazon)
• 1 1/2 t grated ginger
• 1 t corn flour (buy it on Amazon)
• 4 T water

In a saucepan, mix all ingredients except the corn flour and water and bring to a boil. In a separate bowl, whisk together the corn flour and water. Pour into the sauce and stir to combine. Allow to return to a boil, stirring regularly, so that the sauce thickens. Remove from heat and allow to cool. Store in the refrigerator.
