Hi, Gawain. Thanks for your comment and your recent order. All my sauces are produced in an industry certified commercial kitchen in Hampshire, in the PO postcode area of Portsmouth. Each batch I cook yields circa 450 bottles each flavours are hand-crafted from start to finish. All five of the sauces in my range are still based on the original recipes I developed in my home kitchen back in 2015 and are now proudly stocked in over 130 independent outlets across the South of England. To read more check out the 'Founder' page on my website and also the 'Stockists' page for my stockists map. Thanks for your question. Which one is your favourite? Warm regards, Liam.
