Other spices and herbs: root ginger, cloves, pineapple, lemon grass, teabag, cinnamon, cardamom, star anise,pimento berries, lemon and lime rinds or whole, alligator pepper etc. (use only one or two).
Rinse the zobo thoroughly in a bowl of water, to remove any grit.
Place it in a small pot, add the water and spice, herb or fruit, bring to a boil. Boil for 10 minutes and take off the heat.
Leave to steep and cool for about 30 minutes. By which time the spices would have infused their flavour and essence into the liquid.
Strain with a cheese cloth, a very fine sieve or a piece of chiffon fabric.
Put the liquid back in a clean pot. Add sugar and lemon juice and boil till all sugar is dissolved. Take off the heat.
The longer it is boiled, the thicker it will become and it will thicken further when it cools down.
To serve, simply dilute with water or soda water for a fizzy drink.
