Every Reunionese family with relatives elsewhere in the world regularly sends them parcels laden with local flavours. What's in them? Mangoes, pineapples, samoussas, corks, turmeric, rum... and tons of love.
These products are available in mainland France, the United States and Switzerland... but it's true that the 'taste' of local produce is unique.
A letchi bought in mainland France will never have the same flavour as its counterpart picked on Réunion. It will lack the trace of Réunion's soil and the love of the person who produces and ships it.
