Ingredients

  • 150 ml vinegar
  • 100 g sugar
  • 50 g ketchup
  • 2 tbsp cornstarch
  • 200 ml water

Steps

  1. In a saucepan over medium heat, combine the vinegar, sugar, and ketchup, stirring until the sugar dissolves, about 5 minutes.

  2. In a separate bowl, mix the cornstarch with water to create a slurry. This will help thicken the sauce.

  3. Once the sugar has dissolved, slowly add the cornstarch slurry to the saucepan while stirring constantly. This prevents lumps.

  4. Continue to cook the sauce for an additional 5-10 minutes, or until it thickens to your desired consistency. Keep the heat steady to avoid burning.

  5. Taste the sauce and adjust the balance of sugar and vinegar as needed, adding more sugar for sweetness or vinegar for tang.

Why this works

Sweet and sour sauce achieves its signature flavor through the careful balance of acidity and sweetness. Vinegar provides the necessary tang, while sugar counteracts this acidity, creating a harmonious blend that tantalizes the taste buds. Ketchup adds complexity and a hint of umami, enriching the sauce's profile. The use of cornstarch as a thickening agent allows the sauce to attain a silky texture without becoming overly heavy. If the sauce seems too thick, adding a little more water can help reach the desired consistency. Conversely, if it appears too thin, continue cooking to allow more water to evaporate or add a little more cornstarch slurry. This flexibility ensures a perfect sauce every time, tailored to your liking.
