To make your own extract, you will need fresh or frozen pandan leaves (can be purchased from Asian grocery stores). For this recipe, you will need about 2 to 3 leaves measuring about 30cm each. Cut them into 2 inch sizes and add them to a food processor. Add the milk (measurement as provided in the recipe card) and process the leaves until fine. Strain the pandan juice with a fine mesh sieve or cloth. Squeeze out all the pandan extract from the leaves and discard the pulp. Use the pandan extract infused milk in the recipe as indicated. You can skip the pandan extract mentioned in the recipe card.
