- Granulated Sugar - Sugar sweetens up the sauce and thickens it.
- Rice Wine Vinegar - Gives the sauce a kick of acidity along with a natural sweetness from the rice.
- Malt Vinegar - Another type of vinegar that adds a distinct sweetness and malt flavor to the sauce. Substitute white vinegar or apple cider.
- Ketchup - A key ingredient in most Amai sauces, ketchup adds a lovely sweetness, acidity, tomato flavor, and red hue to the sauce.
- Tamarind Paste - This ingredient is key in giving the sauce its characteristic sour flavor. It can be found in most Asian markets or online.

Combine the ingredients: To a small saucepot, add the sugar and vinegar, and turn to medium-low heat.
Dissolve the sugar: Using a whisk, stir the sugar and vinegar together until the sugar completely dissolves into the sauce.
Mix the sauce: Add the remaining ingredients including, ketchup, tamarind paste, and soy sauce and whisk to fully combine.
Boil and thicken: Bring the mixture to a boil, then reduce the heat down to a simmer. Cook for 25 minutes or until the sauce becomes thick and sticky. Remove any foam that may form on the top with a spoon.
Cool and store: Remove from the heat and let the sauce cool before storing in an airtight container in the fridge.
This recipe makes about ¾ cup of Amai sauce which is the perfect amount to dip 20 gyoza or potstickers. It can also be used as a sauce on Japanese curry or noodle dishes.
Allow the sauce to cool before storing as hot liquid with sugar can cause serious burns if you're not careful.
The sauce will thicken as it cools, so if you want a thinner consistency, simply add a little water when reheating.
Serve amai sauce warm or cold.
Variations & Substitutions
Rice wine vinegar can be replaced with white vinegar or apple cider vinegar if desired.
If you don't have malt vinegar, you can use an equal amount of rice wine vinegar or white vinegar.
The tamarind paste can be replaced with fresh lime juice if you can't find it. However, the sauce will not be as sour.
If you don't have dark soy sauce, you can use regular soy sauce or even coconut aminos.
Add some heat to the sauce by stirring in a pinch of cayenne pepper, crushed red pepper flakes, or Sriracha sauce.
Storing: To store, allow the amai sauce to cool completely then transfer it to an airtight container and keep it in the fridge for up to two weeks.
Freezing: I do not recommend freezing this sauce as the texture will change when thawed. If you must freeze it, transfer the cooled sauce to a freezer-safe container and freeze for up to three months. Thaw in the fridge overnight before using.
Yes, simply use gluten-free tamari in place of the soy sauce. You can also use coconut aminos instead for a similar flavor. Check all other ingredients are gluten free.
Amai means "sweet" in Japanese. This amai sauce is sweet, sour, and slightly savory making it the perfect dipping sauce for potstickers or to use on Japanese curry dishes.
