Stir-fry Prawns with Salted Egg Yolks

Trying to replicate a dish that I had in a Chinese restaurant in Bugis. I forgot the name of the restaurant. Think it's Nanxiang or something like that... Anyway, you should try out this dish if you are there. Double thumbs up for it!

Especially for my husband, he love this dish to bits. He has been pestering me to cook this dish for the longest time. And after gathering much information and researches plus a couple times of failure, I finally got it right. Though not as fantastic as the chef's creation, but good enough to earn a compliment from my husband. For those who do not know him, anything that passed his QA/QC, it can't be too bad.

Ingredients
250g of prawns
2 salted egg yolks
1 tablespoon of butter
1/2 teaspoon of sugar
Salt

Preparation
Deep fry the prawns and remove from heat when they are just cooked.
Set aside and drain.
Steam the salted egg yolks for 5-8 minutes.
Mash up the yolks.
In a pan, melt a tablespoon of butter.
Add in the mashed egg yolks and stir.
Allow the yolks to blend into the butter to form a sauce.
Return the prawns to the pan.
Add in a pinch of salt and 1/2 teaspoon of sugar.
Stir well and serve immediately.

*** Update: The restaurant is NanXiang Steamed Bun Restaurant. More information here ***
