Sweet & sour tofu is something I never order in a Chinese or Thai restaurant in Australia, as it often tends to be pretty naff when it’s made for the western palate – too sweet, not enough balance of flavour. But when I learned to make it in Thailand from my cooking teacher, I discovered sweet & sour can be a veritable explosion of complex flavours and textures, provided you’re good at the balancing act required 😉
The secrets to a fabulous sweet & sour? Well, the secret’s in the sauce, of course 😛 My version is heavy on the sour, thanks to lime juice, and adds plenty of pep with a teeny bit of chilli and soy sauce. I also go heavy on the garlic and ginger to round out the flavour. Oh, and you have to use a slighly tangy tomato sauce for best effect – none of that nasty sickly-sweet ketchup stuff 😡
Here’s how to knock up a sweet & sour tofu that’ll have your guests begging for more… 😉
Flavour: Sweet & sour, duh!
Serves: 4 as a side dish, or 2 as a main meal
Ingredients:
- quarter cup of good quality tomato sauce
- 6 tablespoons soy sauce
- juice of half a lime
- 1 tablespoon rice vinegar
- 1 tablespoon sugar (I prefer to use coconut sugar or rapadura)
- 2 tablespoons sunflower oil
- a few drops of sesame oil (go easy, as the flavour is strong)
- 250g firm tofu
- 3 tablespoons cornflour or rice flour
- 1 small onion, cut into large chunks
- 2 cloves garlic, finely minced
- 1 teaspoon minced fresh ginger
- 1 bird’s eye chilli, finely chopped – this is just to add a little pep, not to make the dish spicy
- half cup/whole cup of the following veggies – you choose your ideal combo:
- carrots – finely & diagonally sliced
- cauliflower – small florets
- Asian green vegetable of your choosing
- cucumber – cut into large chunks (gotta try this – cucumber is sublime in sweet & sour)
- 2 spring onions – cut white/light green parts into 3-4cm lengths, and finely chop the soft green end parts; keep ’em separated
- 1 cup of water (you may well need less, so go easy)
- sprinkle of white pepper
Optional extra veggies:
- Capsicum – red, green, yellow, or a combo
- Tomato – cut into large chunks
- Zucchini – cut into large chunks
- Pineapple chunks (please use fresh pineapple!)
Directions:
- Prepare your veggies how you like, and keep them separate as you prepare the rest because you’ll be adding them at different stages
- Cut your tofu into chunks – I like 1-inch cubes, or 1-inch by half-inch squares – up to you how you do it
- Dust the tofu with half the cornflour/rice flour, making sure each piece is coated – set aside on a plate ready for frying
- In a small bowl, dissolve the sugar and the rest of the cornflour/rice flour in the soy sauce, vinegar and lime juice, add the tomato sauce, and set aside
- Heat both sunflower and sesame oil in a wok over high heat
- Toss in your tofu when the oil is hot so you get a quick-n-crispy fry going – this is how to get a deep-fried finish on a shallow-fried morsel 😉
- Amateur tip: make sure you keep the tofu chunks separate to they don’t stick together, and toss them in the wok to turn them, rather than trying to flip them with a spatula
- Once your tofu is golden and crispy, toss in your onion, garlic, ginger and chilli – stir-fry for one minute
- Toss in your carrots and cauliflower, and stir-fry for 2 more minutes
- Add the green veg and the white/light parts of the spring onion, and stir-fry for one more minute
- Stir in your sweet & sour sauce mixture, and add the water gradually as the sauce thickens – you should see it turn thick and glossy very quickly – only add extra water if it thickens to the point of looking too dry, as you want it nice and saucy but not runny
- Stir in the cucumber chunks, and cook for one more minute
- Take off the heat, transfer to a serving dish, and sprinkle with the green parts of the spring onion – serve immediately with piping hot jasmine rice
