Roc Blox: frequently asked questions
What is a sour cable sweet?
A sour cable is a long, thin, sweet-style sweet (typically 8-15cm in length, the diameter of a pencil) coated in sour sugar or citric/malic acid crystals. The cable format gives a distinctive eating experience , you can bite, tear, twist or layer the cable rather than just chewing like a gummy. The sour coating delivers immediate tang on first bite, with the sweet interior balancing the sourness. Common pick-and-mix favourite.
Are Roc Blox vegan?
Vegan status varies by Roc Blox variant. Some variants use gelatine and are not vegan; others use pectin or starch as a gelling agent and are vegan-suitable. Always check the back of each individual pack for confirmation. For confirmed vegan cables, see our vegan sweets range which lists confirmed vegan-suitable options.
How do you eat sour cables?
Sour cables can be eaten in several ways: bitten in chunks like a normal sweet, sucked along the length to draw out the sour coating before chewing, torn into smaller pieces for sharing, or twisted together with multiple cables to combine flavours. The chewy texture suits all approaches. Drinking water alongside eating helps neutralise the sour acidity for sensitive mouths.
Why do sour sweets make your mouth tingle?
The tingling sensation comes from the high acid content (typically citric acid or malic acid) reacting with your saliva and the cells lining your mouth. The acid activates the same sour-taste receptors that respond to lemons and vinegar but at much higher concentration. Some people experience this as pleasant and refreshing; others find it uncomfortable. Mouth ulcers, tongue tenderness and salivation are normal responses to high acid loads in sour sweets.
