Customers will be able to sample a range of different gin and tonics before deciding which pairings to include in their bespoke crackers. Gin brands will include Hendrick’s, Pink Pepper, Edinburgh Gin and Slingsby Rhubarb Gin, with crackers available to purchase individually at an RRP of £8 (US$10.50) or in gift sets of four, priced at RRP £32 (US$42).
