How to make the best stir fry sauce

This umami stir fry sauce is so flavourful and delicious. It’s made with simple ingredients and easily customizable to suit your tastes.

Soya sauce is the savoury base of the sauce, with water to tone down the salty flavour. Brown sugar for sweetness, rice vinegar for some tanginess. Sambal oelek provides heat and garlic flavour, but you can use sriracha if you want to. Finally, cornstarch to thicken the sauce.

Choosing the right tofu for stir fry

I recommend using extra firm tofu, but firm or medium firm will also work fine. I wouldn’t choose anything softer than medium firm though, as softer tofu tends to fall apart.

How to make tofu stir fry

Press the excess moisture out of the tofu brick, and cut it into pieces. Toss in soya sauce and corn starch, then fry over medium heat until crispy. Remove from the heat.

Heat a drizzle of oil or sesame oil over medium heat and cook the aromatics, like ginger and garlic, until fragrant. Then add the vegetables and cook for a minute. Then, add the tofu back in along with the udon and sauce. Let the sauce heat up. The heat will soften the udon noodles, making them easy to pull apart. Give everything a good stir and then serve! See how easy it is?

I cook the tofu first, to get it nice and crispy. It has a base layer of flavour too, from tossing it in soya sauce before cooking. Remove the tofu from the pan, and then cook the aromatics, like ginger and garlic, until fragrant.
