Chocolate limes are lime flavoured boiled sweets with a chocolate centre. The UK retailer Sweets and Candy describes them as lime flavoured boiled sweets with a smooth, chocolatey centre.

What is in them

Chocolate Limes, as listed by Sweets and Candy. Sugar, glucose syrup, water, dark chocolate containing soya, icing sugar, flavouring, and the colours E133 and E102. The retailer lists them as suitable for vegetarians.

The shell is a boiled sweet, made by cooking sugar and glucose syrup until almost no water is left, and the dark chocolate forms the centre: see how are boiled sweets made?

Where the green comes from

The recipe lists only two colours: brilliant blue, E133, and tartrazine, E102, which is yellow. Mixed together, blue and yellow make green. Tartrazine is one of the six colours that must carry the warning may have an adverse effect on activity and attention in children, and the listing shows it: see the Southampton six colours
