How Many Syns in Blue Dragon Sauces?

By Jenny Updated

Blue Dragon is one of the most recognisable names on the British supermarket shelf when it comes to Asian-inspired cooking sauces, and the good news for Slimming World members is that the range tends to be surprisingly kind on the syns. Whether you are throwing together a quick weeknight stir fry, glazing chicken thighs for a fakeaway, or jazzing up a tray of roasted vegetables, a tablespoon or two of a Blue Dragon sauce can transform a Speed-heavy plate into something that genuinely tastes like a treat.

Most of the thinner soy-based and oyster-based sauces come in at around 1 syn per tablespoon, while the stickier, sweeter hoisin and sweet chilli varieties creep up slightly because of their higher sugar content. That said, even the priciest entries in the range rarely cross 2.5 syns per tablespoon, which makes them very workable within a daily allowance.

The trick is to measure rather than glug straight from the bottle, because it is genuinely easy to pour 50g over a pan in one go without thinking. A good habit is to spoon the sauce into a small ramekin first, count the syns, then add it at the end of cooking once your meat and vegetables are already seared and resting.

Blue Dragon also do thicker stir fry sauce pouches and individual sachets, which can be heavier on syns per pack but useful for portion control because the serving is fixed. Pair any of these with plenty of peppers, mangetout, beansprouts, spring onion and chilli for Speed, then serve over Free rice or noodles.

You get the full takeaway hit, the heat, the gloss, the umami, without the regret on weigh-in morning.
