Heat about 3 tablespoons of oil to 70% heat, pour into the bowl of curry powder and stir together. (This is the method how I make curry sauce for the shrimp.)
Dice the onion, garlic, and ginger.
Arctic shrimp are naturally thawed in advance, and oil is poured into the wok.It is heated to 80% heat, and the shrimp are put down and quickly fried for about 20 seconds.
Pour out the oil (leave a little base oil), stir-fry the onion, garlic and ginger. Then add the proper amount of curry/oil.
Stir all the contents together, and let simmer for a few minutes.
Put the fried shrimp in and add an amount of hot water to submerge the shrimps, put sugar and salt and bring to boil.
Then pour in the 2 tablespoons of fresh milk and boil again. Add the butter/flour melted in advanced.
Pour into a metal baking pan and put it in an oven, that has been preheated to 200° C, for five or six minutes. Take it out and serve!
