How Many Syns in Cornflour?

Cornflour is one of those pantry staples that quietly rescues countless dinners, thickening gravies until they cling to roast potatoes, glossing up stir-fry sauces, and giving homemade custard that velvety wobble. On Slimming World, however, it earns the dreaded syn label because, despite being used in tiny amounts, it is essentially refined starch with very little nutritional return for the calories it brings. Every tablespoon you whisk into a sauce will cost you roughly 1.5 syns, which sounds modest until you realise how easy it is to tip in two or three tablespoons without thinking, especially when you are chasing the consistency of a takeaway-style sweet and sour or a thick beef stew.

The good news is that cornflour is rarely the main event in a dish, so you can usually budget for it within your daily 5-15 syns allowance without much fuss. A teaspoon stirred into a sauce for four people works out at a negligible cost per portion, particularly if you slurry it properly with cold water first to avoid lumps. Many slimmers swear by reaching for it sparingly when a recipe genuinely needs body, rather than relying on it as a default. Reducing sauces over a higher heat, blending in roasted vegetables, or using pureed cannellini beans are all syn-free tricks that mimic the silky finish cornflour provides.

It is worth remembering that cornflour behaves differently from plain flour, thickening at a lower temperature and producing a glossier, more translucent finish, which makes it ideal for fruit pie fillings, lemon curd, and Chinese-style glazes. Used thoughtfully, a small dusting or slurry can transform a watery curry into something restaurant-worthy without derailing your week. Keep a small jar to hand and measure rather than pour straight from the bag.
