I have allowed my milk to cool down and added two tablespoons of yoghurt.
Am I supposed to leave the vessel open? Cover it with something?
Also, I don't have an incubator, can I leave it in the sun, to reach the very warm temperatures required?
If I am just patient, and allow it to rest at a lower temperature, will it still thicken eventually ?
I am in Nicaraugua so it is pretty warm here , in the daytime.
Thank you.
