Homemade Okonomiyaki Sauce

Ingredients

• 1/4 cup oyster sauce (76 g; I used Lee Kum Kee Premium Oyster Sauce; if you‘re allergic to shellfish, use Lee Kum Kee Vegetarian Stir-Fry Sauce)
• 3 Tbsp sugar (39 g; or more, to taste)
• 1/2 cup ketchup (136 g; to taste)
• 7 Tbsp Worcestershire sauce (105 g; I used Lea & Perrins Worcestershire Sauce)

Instructions 

1. Gather all the ingredients.
2. Combine ¼ cup oyster sauce and 3 Tbsp sugar in a small bowl. Mix with a spatula or whisk until the sugar is completely dissolved. Tip: I used organic cane sugar.
3. Add ½ cup ketchup and 7 Tbsp Worcestershire sauce. Tip: I used Heinz Simply Tomato Ketchup. Some ketchup is sweeter than others, so please adjust the amount of sugar to taste.
4. Mix it well, taste the sauce, and adjust it according to your liking.
