HP, the UK's no. 1 brown sauce, has been adding oomph to your favourite dishes since 1903. The original recipe was invented and developed in 1899 by Frederick Gibson Garton, a grocer from Nottingham. Garton sold the recipe for the sum of £150 to settle a debt with Edwin Samson Moore, the founder of the Midlands Vinegar Company, who launched what we know and love today as HP Sauce.
