In a bowl, mix cornstarch and a little salt until well combined.
Briefly fry the mixture until cooked; do not overcook the prawns.
In another pan, heat oil and add butter.
While stirring, add an egg yolk and continue to stir-fry with 7 cloves of garlic, kari leaf, and some red chili peppers for a short time.
Add 1 cup of milk and season with salt.
To enhance the flavor, add Sunquick orange essence in two corners of the pan before adding the previously fried prawns.
Stir well until everything is evenly coated. For a thicker texture, you can add more milk but Hamdan prefers it slightly thick.
