I don't cook with exact quantities, or with same herbs every day, I do it by smell, and by feeling, so my recipies are little unorthodox, and I'm not internationaly kitchen educated so I don't know if these recipies are common knowlege
4 day chicken/veal soup. Not really a soup but I dunno how to call it
Idea is that if family wants soup every day, to not do the cooking every day, but to make the base first day, and then modify for every meal.
And also to use it as additions while cooking different meals, for that extra flavor
U need 8-10l pot, which U can put in the fridge. Sealed ones are the best.
A lot of different vegetables.
I usually go with minimum 6 large carrots, usually 9.
1/2 onion
1/2 Kohlrabi (that google says is keleraba

)
1/2 parsley root
slice of celery
some parsley leaves
1/2 Parsnip root
sea salt
ground pepper
One chicken back (what U get when removing legs and white meat).
200-300g peace of nice veal, from the neck is good for cooking
Sometimes I put some leek in it, or some other vegetables I have in the fridge.
Water to 80% of the pot.
Boil for minimum 1.5h
That's the base. I keep it in the fridge in express pot, and take fluid, meat and carrots when I need it as addition for other meals.
For first few days, I just take the fluid and either:
1. Boil noodles in it, decorate with chopped parsley leaves, and few carrots from soup
2. Mix an egg in a cup, add some salt, chopped parsley, and then mix it slowly with boiling soup.
3. same as 2 but add a little milk to it. If U like sour broth, U can add sour cream.
4. add wheat dumplings to it. 1 egg , some salt, wheat gritz (I hope that's the word) and some chopped parsley, mix it in a cup. Has to be so thick to not fall out of upside down cup. Put it in fridge for 10min, take small dumplings with spoon and add to boiling soup.
5. mash the vegetables in soup, take the chicken meat from soup and separate it with fork in small strings, then add 2. or 3.
