To make a drink to cure coughs, colds, congestion and chest ailments:
Put a small handful of dried carrageen into 1.5 litres of water and soak for 10 mins until the carrageen is soft. Bring to the boil. Reduce heat and simmer for 10 – 15 mins. Strain the liquid through a sieve. Pour 1/3rd into a glass and add lemon juice and honey (or blackcurrant cordial such as ribena) to taste. Drink a glass each night for 3 days. (Warm liquid gently before drinking).
