If you aren’t feeling well, especially if you have an upset stomach Italians say that you are debole di stomaco; this seems to be a common malady with Italians. The home cure is to eat in bianco – white food (bianco is Italian for white). In bianco is the culinary term used to refer to a dish, which is served plain and with little seasoning.
Broth, boiled rice, boiled chicken/veal, certain boiled vegetables, steamed white fish, bistecca di vitello a bagnio maria (veal steak cooked in a baine marie), latte di mandorla (almond milk) and bianco mangiare (dessert= thickened almond milk) are some of the foods which are considered mangiare (food) in bianco.
The perfect in bianco food and the cure for any ailment of course, is brodo (broth).
I usually use a whole, organic chicken and eat the flesh after I have made the broth. If I use a veal shin I also eat the flesh (try it with a salsa verde). If I am eating the meat, I remove the chicken or veal from the broth after about 60-80 minutes of gentle cooking and then evaporate the broth on high heat.
Obviously the more solids, the more taste. To concentrate the flavours, cook the broth for longer and towards the end of cooking, leave it uncovered to evaporate.
If you do not wish to eat the meat, fleshy bones from organic chickens are a suitable substitute. Because stock is the foundation for cooking, the quality of the bones is important, cheap bones from battery hens will not produce flavourful stock and it is likely to be full of concentrated chemicals.
Gallina vecchia fa` buon brodo (Ancient Italian proverb).
An old chicken makes good broth.
