This delicious Japanese-style Amai sauce is so quick and easy to make. Perfect with noodles or as a Wagamama-style dipping sauce!
🍴 Why you will love this recipe
Amai Sauce is essentially a sweetened and thickened soy sauce, which is perfect for dipping, or serving over noodles, grilled vegetables and tofu. It is sweet, sour and deeply savoury all at the same time - totally delicious and so easy to make!
If you've ever eaten at Wagamamas (or any Japanese ramen bars) you'll probably be familiar with this delicious sauce. It is often served with gyoza dumplings, or as a sauce with the traditional yaki soba noodle dishes.
A traditional Amai might contain more ingredients and be simmered for longer, but I've simplified and speeded up the recipe here, and I think this quick sauce is just as good as the original!
📝 What you need
Soy Sauce is the main ingredient in amai sauce. It is made from fermented soya beans and gives a salty, umami flavour to the sauce. You can use a lower-salt soy sauce if you prefer, but taste and adjust seasoning before serving.
Rice Vinegar is sweeter and more delicate than western vinegars. You can use half-and-half rice and malt vinegar if you like.
Tamarind Paste gives the sour taste to the sauce. It is made from a dark, sour and sticky pod that grows in a pod on a tamarind tree.
