Trusted By Professionals 

"At Charlottes Jersey Ice Cream Parlour we have been making some of our ice cream with Zùsto. We found by replacing the sugar content and in our ice cream with Zùsto, it did not effect the taste or the freezing quality. Customers couldn't tell the difference."

Eric Joyce, Ice Cream Chef at Charlotte's Jersey ice Cream Parlour

"We have 2 exciting new products available today for our diabetic customers 😱🙌 Our friends @zustouk sent us some of their lovely no sugar, sugar to try. So we have a flourless chocolate cake which is completely sugar free using zùsto sugar instead and a reduced sugar vegan chocolate & hazelnut brownie."

Blackberries Patisserie

"The sugar substitute really is amazing and delicious to taste. I thought it would have an after taste like Stevia but it's great. Will be purchasing more in the future". 

Cakes By Shahana

"I have finally had a chance to use your sample today, and I am incredibly impressed! I made a gluten free and dairy free cherry bakewell traybake (as I specialise in Free From cakes).

The batter was exactly the same consistency as usual, it baked in the same amount of time, and upon a taste test it was delicious and sweet. I wouldn't have known the difference! I use sugar syrups on my cakes to keep them moist, at first I was apprehensive I would be able to use Zùsto for a sugar syrup because of the way it reacts with wetness, but after simmering it in water (and almond essence) it had a normal sugar syrup consistency and cooled well on the cake."

Gemma, Little Gem's Cakes

I've been asked every now and again at markets if I do a low sugar jam for those with diabetes and other conditions, so I was interested when I received an email from Zùsto asking to review their sugar free sugar.

I liked the taste of raw Zùsto - kind of like a candyfloss.  For me, the finished preserve tasted the same and both a good set."

Christine, Heavenly Hedgerows
