British plant-based syrups brand Sweet Freedom has launched what it calls its ‘boldest creation yet’ – Mystery Syrup, a pink syrup with a mystery flavour.

Though the ‘top secret’ flavour has not been named due to trademark laws, the brand’s managing director, Nadine Maggi, said consumers will “know exactly what it is” as soon as they taste it. “Let’s just say it’s fruity, fun, and has a bit of a cult following already,” she added.

Consumers are invited to submit their flavour guesses on the company’s website, where the sauce will be available exclusively, for the chance to win a prize.

According to Sweet Freedom’s website, the sauce is ‘loved by toddlers and grown-ups… who sometimes pretend they’re buying it for the kids’.

This has led to speculation that the syrup is inspired by Calpol, a widely used UK children and toddler’s medicine brand designed for pain and fever relief, available in liquid form with a well-known strawberry flavour.

It wouldn’t be the first food and beverage item to be inspired by the nostalgic medicine product – earlier this year, Leeds-based bakery Get Baked released a limited-edition cookies product with a strawberry glaze and powdered sugar, playfully named ‘Cease and Desist’ Cookies in response to the legal issues associated with using Calpol’s brand name to market the product.

Other flavour guesses from consumers on the brand’s Facebook page included Premier Foods’ Angel Delight and Marks & Spencer’s Percy Pigs.

The Mystery Syrup is made from apples and carob, containing no refined sugar or artificial sweeteners. It contains 13 calories per teaspoon and can be used across versatile applications, including in beverages, drizzled over breakfast and desserts, stirred into yogurts and smoothie bowls, or used in home baking.
