I’d had a tin of chestnut puree in my cupboard for over a year, with no idea what to do with it. I’d bought it with every good intention to make some Christmassy treats last year but never got round to it.

So I recently came across it lurking in the back of the cupboard and discovered that it’s very low in syns!

These are really easy to make, and take no time at all. With a rich filling, you will be fooled into thinking that these are more than 1 syn each!

Synning the sweetener

As you will probably know Slimming World brought out some new recommendations regarding the syn value of granulated sweeteners last year. This means that…

Where there is 1 tbsp or more being used per serving they recommend members count 0.5 Syn per tbsp. If using smaller amounts, like a pinch or teaspoon, there’s no need to worry about Syns at all.

The recipe for this Low Syn Chestnut and Chocolate Tarts uses 2 tablespoons of sweetener and is divided into 16 portions. That’s 1/8 of a tablespoon of sweetener per portion, so unless you are having 8 of these there’s no need to add any syns on for the sweetener itself.

To make these, Low Syn Chestnut and Chocolate Tarts you will need….
