Low Sugar Sweet and Sour Sauce — The Takeout Swap
Sweet and sour sauce is one of those things that sounds like it's half healthy — the sour part, presumably. Then you check the label and find 22 grams of sugar in a quarter cup. That's more than five teaspoons in a sauce you're pouring over dinner.
This version uses fresh pineapple for natural sweetness and monk fruit to balance it — the result is bright, glossy, properly tangy, with little pockets of pineapple that taste like actual pineapple rather than a memory of pineapple from a tin.
It pairs beautifully with crispy chicken, prawn stir-fry, or honestly just used as a dipping sauce while you pretend you're not eating it straight.

Taste and adjust — more rice vinegar for tang, more monk fruit for sweetness. Serve with crispy chicken or shrimp stir-fry.
Using Fresh Pineapple for Natural Sweetness
Traditional sweet and sour sauce relies on canned pineapple juice, white sugar, and sometimes ketchup (which also contains sugar) for its characteristic flavour. Fresh pineapple provides natural fruit sweetness alongside real texture, while monk fruit handles the extra sweetness needed to balance the vinegar.

Common Mistakes
- Using tinned pineapple. It goes mushy and the extra syrup throws off the balance. Fresh is the only way here.
- Boiling too hard. A gentle simmer keeps the pineapple intact and prevents the sauce scorching at the edges.
Storage
Store in a sealed jar in the fridge for up to 5 days. Reheat gently on the hob, adding a splash of water if it thickens too much.

Frequently Asked Questions
Can I use tinned pineapple in a pinch?
Yes — drain it very well and pat dry. Use pineapple in juice (not syrup) and reduce the monk fruit slightly since it will be sweeter than fresh.
What does this go well with?
Crispy chicken, prawns, pork, tofu — anything that benefits from that sweet-sour coating. Also excellent as a dipping sauce alongside the Thai Peanut Sauce for a full spread.
