During this time, the beans change color, they are left. If you taste it, it should be boiled, but not completely dissolved, do not make porridge out of it. Better a little more "al dente" than fleashka.
Suitable for salt, you can leave it to boil without a lid, to make the sauce a little thicker, about 10 minutes.
Optionally at the end you can add a little greenery, I did not put.
