That was the temperature of gentle simmer for me. I make cottage cheese every week and the directions are for it to come almost to simmer and just as bubbles start to break on the surface the temperature is at 197°.
I don't know if it is just my imagination but to me, the viscosity of the liquid seems to affect the temperature at which it maintains a simmer.
