This is a recipe I cooked up for my friend Gerwyn when he came down with a chesty cough as a secondary infection following a fever, poor chap.
Makes about a days’ worth of doses.
2–3 inch piece fresh ginger, unpeeled, thinly sliced
2 pts (1.2 l) cold water
1 tsp powdered licquorice root
2 tsp blackstrap molasses & 3 tsp golden syrup
(or: 2 tsp black treacle & 3 tsp light brown sugar; or: 5 tsp honey; etc.)
1–2 oranges, juiced
3 shots (75 ml) white sambuca (40% ABV)
1/2 tsp ground cinnamon
Put the cold water and sliced ginger in a pan, bring to the boil, and simmer for about an hour (until reduced to 1/2 pt or less). Add licquorice root and simmer for a few minutes.
Add sweeteners and stir on very low heat until dissolved.
Remove from heat and add extras. Top up to 1 pt (600 ml) with hot water and keep in a thermos. Sip or glug as desired.
Additional: Gerwyn also recommends mixing with a hot blackcurrant drink.
