Bloody Mary lovers can celebrate the Fourth of July with Mott's strange and fishy (but tasty) Clamato juice - tomato juice with clams.

A hot seller at Harrods, Clamato juice comes in regular flavour as well as 'spicy for extra zing. Clamato juice is particularly good for that marvellous morning-after lifesaver and vitamin-enriched pick-me-up, the Bloody Caesar.

Into this goes clamato juice, vodka, lemon juice, Worcester sauce, tabasco, celery, lime, celery salt and pepper.

Eye-watering, tongue-twisting, chest hair-growing stuff.

Mott's Clamato juice costs pounds 3.50 a litre at Harrods, 87-135 Knightsbridge, S1X 7XL (071-730 1234) Mon/Tues/Sat 10am-6pm/Weds/Thurs/Fri 10am-7pm.
