In a large saucepan, blanch the marrow bones over high heat for 10 minutes.
1.5 kg big beef bones
Meanwhile, cut the onion in 2, slice the ginger lengthwise in several slices and slice the whole head of garlic in 2, leaving the skin on.
1 onion, 1 large piece of ginger, 1 head of garlic
Preheat the oven to maximum temperature in grill mode (heat from the top). Put what you sliced earlier on aluminum foil and a cake, and bake until slightly blackened (about 15min). Be careful not to char them either, but there should still be a layer of "black".
Pour the blanched bones into a colander. Clean the pan
Place all your spices in the cheesecloth.
2 cinnamon sticks, 1 tablespoon coriander seeds, 1 tablespoon fennel seeds, 5 star anise, 5 pods black cardamom, 10 cloves
Cooking the broth
In a large saucepan, place the sachet of spices, the large piece of beef, the herbs grilled earlier, the fish sauce, the sugar, the salt, the bones...
1 kg of brisket, 1 lump of rock sugar, 3 tablespoons salt, 230 ml of fish sauce
Fill to the brim with water, after adding the remaining ingredients.
Bring to the boil, uncovered, then place over medium-low or even low heat and simmer for 3 hours, stirring occasionally.
After 20-30min, remove the large piece of beef. Let it rest for a while, then put it in the freezer for 30 minutes.
Then slice it as thinly as possible
At the same time (after 30 min of cooking), add the meatballs to the broth if applicable.
1 package of beef balls with tendon meat
Finishing the broth
After 3 hours, filter the broth through a very fine metal strainer. If you taste it at this stage, it will be far too concentrated/rich/salty.
Collect the dumplings, place in an airtight container and store in the fridge. Onion confit is delicious eaten straight from the tin if you're feeling hungry after all that cooking.
Let the broth sit for a few hours (covered) before storing in the fridge overnight.
The next day, when the fat has solidified on top, remove about 80% of it with a spoon. Leave a little for flavor. Keep the rest for stir-frying - it's delicious!
Just before serving
Start by heating all the stock and tasting. If it's too strong, remove 1 liter, put it in the fridge for another time and replace it with 1 liter of water. Repeat as many times as necessary, tasting.
Cut cooked dumplings in half and place in broth to warm.
Boil the rice noodles according to package instructions, but stop a little beforehand as they will still be cooking in the broth. Alternatively, cook for the same length of time directly in the broth, but make sure you can remove them easily.
450 g rice noodles
To serve
Place the noodles in the bottom of each bowl.
Place a few slices of carpaccio raw steak, very thinly sliced
500 g steak
Place a few slices of the reserved chunk of beef on top.
Place a few pieces of dumpling
Pour the boiling broth over it
Add sriracha sauce, hoisin, coriander, bean sprouts, onion and Thai basil. You name it, we've got it.
Use good quality Vietnamese fish sauce, not Thai! The taste will be all the better for it. I recommend Phú Quốc If you boil the broth for more than 4 hours, the aromatics begin to lose their effectiveness and flavor. In general, herbs and spices release their full aromatic potential after 3 to 4 hours. After this time, it is advisable to replace them to maintain a rich, balanced taste. For a cooking time of 8 hours, a replacement halfway through is ideal. If you're cooking for longer, three batches of spices are usually sufficient.
