Veteran Robert Barrett went from trooping the colour for the household cavalry to being homeless.
When he was re-housed by the Stoll Foundation in Fulham he decided to give something back by setting up his own food stall, and developing his own sauces.
Now Forces Sauces are being sold by a major supermarket - with money going towards the Stoll Foundation and the British Legion.
BBC London reporter Alice Bhandhukravi spoke with Robert Barrett and chef Ed Sargent.
