I want to make l. reuteri yogurt, and i can't find a way to thermostate it.
A yogurt maker machine would be ideal, there are many that have a thermostate. Compared to normal yogurt, which needs about 42°C for 4-6 hours and is not very sensitive of heat, l. reuteri needs 36°C for 36 hours and gets killed off quickly if temperature rises too high. The problem is, each and every yogurt maker i found has either of the following problems:
-is out of stock
-is too expensive (60-80EUR would be the ideal price for me)
-is only sold in USA (euro user here)
-does have a review stating that it's thermostate is unreliable, heating to over 40°C sometimes, killing off l. reuteri.
If yogurt makers are so soykafty, i can't imagine sous vide machines and instant pots, which perform an operation which is much less sensitive of accurate temperature, are better, but i checked and they are very expensive anyway.
Do you have any recommendations on a yogurt maker that is 60-80EUR, sold in EU, in stock, and has a stable reliable thermostate? pic relevant is the Steba JM3 which would be perfect, if it wasn't for it's unreliable thermostate. I even checked state of the art Japanese models and they also have comments saying bad thermostate, getting too hot, etc. Is it possible that the reviewers only got a defective model or is it typical for these types of machines that to be unreliable in their temperature control? If they are defective units, is it frequent or did they just have horrible luck? If everything else fails, i have to make a machine myself with thermotransistors, microcontrollers and relays, but don't want to take on an extra project if not necessary.
