French Pot au feu

I looked over my old recipes and found this one, it is from an old cook book. 

Ingredients (about 6 servings)
1.2 kg beef, short ribs, marrow bones - defrozed
3 L water, room temperature

1 onion
3 cloves garlic
4 cloves
4 thyme
4 bail leaves
4 sage
8-10 pepper grains
1 tbsp salt

2kg vegetables - carrots, leek, turnip, celery

Instructions
1. In a big cooking pot, pour water & place meat, bring to boil and let it boil for 10mins
Remove white foam if there is any, then reduce to low heat, cook for 1 hour

Note: the best will be cocotte such as Staub or Le Creuset (Mine: 37cm oval Staub)

2. Briefly chop onion and mash the garlic
After 1 hour, add onion, garlic, cloves, thyme, bail leaf, sage, pepper & salt into the pot
Leave it cook for another 1 hour at low heat

3. When time is up, add in vegetables, bring to boil at medium high heat
Then reduce the heat to low & leave it cook for 1 more hour

Note: If you use frozen vegetables, you can directly put them into the pot but bring it to boil for 5 mins

Serve hot!
Enjoy!
