Hamburg Steak

Servings: 5

Ingredients
250g minced pork
250g minced beef
1/2 onion, finely chopped
50g breadcrumbs
1 tbsp milk (as needed)
1 egg
1 tbsp potato starch
pinch of pepper
1 tsp vegetable oil
1 tbsp butter

for the sauce:
5 tbsp ketchup
4 tbsp vegetable and fruit sauce (tonkatsu Sauce)
1 tbsp oyster sauce
2 tbsp red wine
2 tbsp water
1 tsp sugar

Instructions
Mix the ingredients for the sauce together to make a demi-glace sauce that will simmer on top of the hamburg steaks; set aside.
Combine the minced meat, onion, breadcrumbs, milk, egg, pepper, and potato starch. Mix until well combined. We recommend using your hands to do this. After combined, divide the mixture into 5 equal parts and form into a small flat oval shape about 2cm in thickness.
Heat the vegetable oil in a frying pan to medium-high heat. Fry each hamburg steak for 5 minutes on each side until brown.
Pour the demi-glace sauce on top of the steaks, and allow to simmer for 5 minutes on medium heat. As a final addition, add the butter.
