In French Guiana people drink ti-punch, the famous Caribbean drink. And it's so humid there that drinking rum at lunch time seems quite cooling. Here's how you make it:
White Caribbean rum
Sugar cane syrup (I suppose a home made sugar syrup would do just as well)
Lime
Ice
Glass
Teaspoon
So. Cut a thick slice or wedge of the lime and squeeze it into the glass and then drop the lime in. Pour some rum over. Then add enough sugar syrup to stop yourself wincing at the rum (that's how it works for me anyway). Stir. Adjust to taste. Add ice cubes if you want. Voila!
Claude from Guyanespace Voyages, who was our tour organiser for the International Space University trip to Kourou, very kindly gave us the essential ingredients for ti-punch. I took the bottles back to Paris with me, thinking a ti-punch would go down very nicely after my long days in the Documentation Centre of the Musee de l'Air et de l'Espace. But it was cold in Paris, and dry. Somehow ti-punch was just too strong there. I gave the bottles to Regis Moello of SNECMA, who works on the Vulcain motor for the Ariane rockets but has never had the opportunity to visit Kourou.
