Step 1

Slice the passion fruits in half and scoop out the flesh into a small saucepan. Mix in the Sugar and Lemon Juice.

Step 2

Place on the stove on low to medium heat and leave to simmer for 10 to 15 minutes (see note 1), or until the sugar has dissolved and the juices have thickened. Occasionally stir to make sure the fruits don't burn. Taste and adjust the quantity of sugar if required (see note 2).

Step 3

Optionally for a thicker coulis: while the coulis is cooking, whisk the cornstarch with one tablespoon of cold water in a small bowl. Pour into the saucepan when the coulis is almost ready. Whisk well to incorporate, then decrease to a low heat and continuously whisk until the sauce has thickened.

Step 4

Leave to cool down for about 30 minutes, then transfer into an airtight jar or sealed container and place in the fridge to cool down completely - about 1,5 to 2 hours.
