Steps

1. Finely mince the onion.
   🕒 01:46
2. Place the minced onion in a heatproof container.
   🕒 01:55
3. Add vegetable oil as needed and microwave.
   🕒 02:15
4. Let the heated onion cool down.
   🕒 02:44
5. Mix in panko breadcrumbs 4 tbsp and milk 2 tbsp, then let it cool completely. [Key Tip!] This helps the onion cool quickly and makes the mixture delicious.
   🕒 02:53
6. In a bowl, combine ground pork 200g, the cooled onion and panko mixture, milk, salt 1/3 tsp, beaten egg 1/2, and whole grain mustard 1/2 tbsp.
   🕒 03:18
7. First, mix by crushing, then once everything is combined, spread your fingers and mix vigorously by rotating until the red and fat parts turn whitish. [Key Tip!] Adding whole grain mustard gives a refreshing flavor that pairs well with white wine.
   🕒 04:34
8. Divide the mixed meat into 2 equal portions.
   🕒 05:12
9. Lightly oil your hands and toss the divided portions back and forth to remove air from the center.
   🕒 05:18
10. Shape them into smooth patties. [Key Tip!] Uneven surfaces can cause meat juices to escape, so aim for a smooth finish.
    🕒 05:39
11. Place the shaped patties in a non-stick skillet without oil.
    🕒 06:04
12. Gently flatten them, but do not press down the center.
    🕒 06:10
13. Turn on the heat and sear one side until golden brown.
    🕒 06:34
14. Once browned, use the side of the skillet to flip them over smoothly.
    🕒 06:42
15. Sear the other side similarly, then add water and cover with a lid to steam until cooked through. Lower the heat.
    🕒 07:12
16. Remove the lid, and once they are puffy with accumulated juices, remove the hamburg steaks and cover with aluminum foil to keep warm.
    🕒 07:54
17. If the skillet has burnt bits from the hamburg steak, wipe it clean.
    🕒 08:26
18. Add all-purpose flour 2 tsp to the skillet with the remaining flavors and sauté briefly.
    🕒 08:52
19. Once the floury smell disappears, gradually add milk 1 cup while stirring. Once it thickens, repeat the process of adding milk.
    🕒 09:43
20. Continue until the sauce thickens enough to draw a 'no' shape, then season with salt to taste.
    🕒 10:14
21. Finish by sprinkling with coarse black pepper to taste.
    🕒 10:37
22. Plate the hamburg steaks and pour the cream sauce over them.
