I was asked to share this recipe, I promised to do so last Monday, but alas, I missed the date.  I apologise for the delay.
Nana’s Barley Water
approx 2 litres

1 light cup Pearl barley –6 to 8 ounces
2 litres water, more or less depending on how thick you want it.
Juice of 1-2 lemons.
Honey or sugar, to taste*

Rinse barley. Put it in a large soup pot with the water.

Bring to a boil, then reduce the heat and let simmer for at least an hour, until the grains are cooked and softened. Add more water if needed.

Strain the liquid and add honey/sugar and lemon, to taste. Cool refrigerate. Use within three to four days.

The finished drink will be cloudy and settle when stored in the fridge, Stir before pouring and drinking.

*Cranberry juice, can be used to flavour the Barley water.

NB: Avoid cranberry juice or extracts if you’re taking warfarin, Cranberry juice can make the effects of warfarin more potent, so there’s a risk of excessive bleeding.

Note: Mammy was known as Nana once the grandchildren arrived!
