I'm planning a Colby and I need to come up with a water bath to hold the curds at 90F. In the past I tried the "kitchen sink" method - adding/subtracting water to keep the temp up, but that seemed to not be too precise. So I thought a temperature controlled would work so I bought the DorkFood DSV. http://www.amazon.com/DorkFood-DSV-Temperature-Controller-Sous-vide/dp/B0088OTON4/ref=cm_cd_ql_qh_dp_t
In tests tonight it (confirmed with an analog thermometer) I set the unit for 90F..it heated it to 96F. Plus the temperature varies as much as 5 degrees either way; i.e. it heats it to temp, overshoots the mark, unit shuts off and it drops 4 degrees. This doesn't seem to be what I need. Has anyone used this?
P.S. I tried uploading pics, but that failed. 0/2 tonight.
