Make The Filling

Spray the salted egg yolks with liquor.

Place them on a heat-resistant plate and cook in the air fryer or microwave for 10 minutes. Afterward, the yolk becomes semi-solid and creamy like the center of a hard-boiled egg.

Use a food processor to blend the egg yolks with cornstarch and milk powder. Transfer to a bowl and set aside. This should give you a sandy or grainy blended texture.

In a bowl of water, soak the gelatin sheets until soft.

Then, stir in warm water with the soft gelatin until well combined.

Pour the gelatin mixture onto the egg yolk mixture and continue stirring until well combined. This should create a creamy and thick mixture.
