Chop the lemon in half or bruise the lemongrass

Bring the cream and sugar to the boil (careful it should just boil but not boil over). Once you see it boil – stay there and boil for exactly 3 minutes.

Take the pan off the heat and stir in the lemon.

Strain this into a jug and cool for 20 minutes.

If you wish to put a crumbled biscuit in the bottom of the receptacle – this is the time to do it. If not gently pour the cream into the glasses.

Refrigerate for 6 hours minimum.

Serve with crushed meringue, fruit and edible flowers or fruit puree such as mango.
