Heat a frying pan on medium and add 1 tbsp cooking oil. Once hot, add 200 g onion (thinly sliced) and fry for about 10 minutes or until soft and golden. Stir occasionally to prevent burning.
Reduce heat to low and sprinkle with a pinch of salt. Cook on low for 20-30 minutes or until dark brown and caramelized. Stir occasionally and add water 1 tbsp at a time to prevent sticking. Once caramelized, remove from the heat.
While you're waiting for the caramelized onions, take 400 g stewing beef and 100 g beef tendon (sinew) cut into bitesize pieces and place them in a bowl with 1 tsp salt and ¼ tsp ground black pepper.
Add 2 tbsp all-purpose flour and mix until evenly coated.
Heat a deep pan or pot on medium and add 1 tbsp butter. Once melted, and the beef and sear on all sides.
Once seared, add the caramelized onions along with 2 cloves garlic, 2 dried bay leaves, 300 g canned tomato, 300 ml red wine, 300 ml water and mix. Place 2 sprigs fresh rosemary on top.
Place a lid on top and bring to boil, then lower the heat and simmer for 30 minutes. After 30 minutes, turn off the heat and rest for 1 hour to allow the flavor to develop.
Once the resting time is up, remove the rosemary, then add 150 g carrot and 100 g button mushroom. Turn the heat back on and bring to boil. When it starts to bubble, add ½ tbsp honey, 2 tbsp tomato ketchup, 1 tbsp Worcestershire sauce, 1 tbsp grated apple, 1 tbsp yellow miso paste (awase) and 10 g dark chocolate.
Simmer for 1 hour with the lid slightly ajar. Check the taste at the end and season with salt and pepper to taste if necessary.
Serve with a few slices of baguette and enjoy!
Notes
Once cooked, cool and refrigerate for 2-3 days.If you don't plan to eat it within that timeframe, freeze for up to 1 month. For best results, remove carrots before freezing.
