Sweet delivery for choc fan Emma

Like a page from Roald Dahl’s Charlie and the Chocolate Factory, an inspired teenager gave sweet makers in Switzerland cause to add a new experimental to one of the most recognisable brands on the market.

Emma O’Keeffe, 14, from Carrigaline, Co Cork, wrote to the Nestlé headquarters last year to suggest that her favourite chocolate bar, the Kit Kat, would be even better if it came in a butterscotch flavour.

Nestlé liked the idea so much it had 20 butterscotch Kit Kat Chunkys crafted by Chris Pearson, a senior confectioner at its product technology centre in York, England.
