Coconut-Pandan Jam (Kaya Jam)

Heat coconut milk and sugar in a medium saucepan over medium. Tie pandan leaves together in a knot and add to pot. Bring to a simmer, cover, and let steep 30 minutes. Uncover pot and return to a simmer.

Meanwhile, bring a medium pot of water to a boil. Whisk egg yolks in a medium heatproof bowl until fluffy. Slowly whisk in half of coconut milk mixture until smooth. Whisk in remaining coconut milk mixture. Set bowl on pot of water (bottom of bowl should not touch water). Reduce heat and bring water to a simmer. Cook, stirring, until mixture is thick enough to coat the back of spoon and an instant-read thermometer registers 180°F, 4–5 minutes. Strain through a fine-mesh sieve into a resealable container or jar; discard solids. Press plastic wrap onto surface and chill until set, at least 4 hours.

Kaya can be made up to 1 week ahead; keep chilled.
