Delicious Hamburgers Simmered In Demi-glace Sauce

• 450 grams Ground beef (or beef and pork mix)
• 1 medium Onion
• 1 Egg
• 100 ml Dried panko
• 3 tbsp Milk
• 1 dash Salt and pepper
• 1 Nutmeg
• 1 can or pack Demi-glace sauce (canned)
• 4 tbsp Tomato ketchup
• 100 ml Red wine (or white wine)
• 400 ml Water
• 1 Soup stock cube
• 1 or bay leaf Bouquet garni
• 1 tbsp Butter
• 1 can or pack Sliced mushrooms in water (canned)
• 1 Carrot
• 1/2 Broccoli

1. Cut the peeled carrot and broccoli into easy to eat pieces, and boil in salted water.
2. Moisten the panko in milk.
3. Chop the onion finely and put into a heatproof bowl.
4. Mix with 1 tablespoon of vegetable oil.
5. Do not cover with plastic wrap; microwave for 4 minutes.
6. When the onion has cooled down, add the rest of the hamburger ingredients into the bowl and mix well with your hands until sticky.
7. Form into patties of the size you like, and pan fry in 1 tablespoon of oil until browned on both sides.
8. You don't need to cook the patties through at this stage.
9. If you can't fit all the patties into the frying pan at once, fry them in 2 batches.
10. Reserve the juices that come out of the meat from the first batch, and return to the pan after the 2nd batch is done.
11. When all the patties are browned, add the drained mushrooms and butter.
12. When the butter has melted, add all the simmering sauce ingredients, and cook over low to medium heat while stirring occasionally until the sauce has thickened.
13. (About 30 minutes.)
14. Transfer to a serving dish, add the broccoli and carrot, pour any sauce remaining in the pan over, and it's done.
15. Optionally drizzle on some fresh cream or coffee cream.
16. Serve with bread on the side to dip into the sauce - delicious!
17. Sweet onions are very watery and can make the burgers fall apart, so use regular onions.
18. Use ground meat with some fat in it, rather than very lean meat.
19. If you add the sauce ingredients all at once in Step 7 the temperature will cool too fast, so after adding the demi-glace sauce add the water and red wine little by little.
