Roughly chop the pandan leaves.

Blend the leaves with just enough water to help them blend smoothly.

Strain the mixture and press it well through a cloth or very fine sieve.

Refrigerate the liquid and let it rest for a few hours.

Let the mixture separate until a dark green layer settles at the bottom.

Carefully pour off the paler top layer.

Collect and use the dark green sediment, which is more aromatic and gives the most natural color.
