If you measure liquid temperature while distilling, you may have noticed that liquid temp can often be much higher than 174 before a still starts producing. Again, the boiling temperature of a solution that is 100% ethanol is 174 degrees.
This will help prevent the onions from becoming mushy in the pickling solution. If the temperature is too high the enzyme will be deactivated, so it needs to be done at the right temperature. Work by Gonzalez et al. suggests that 70C is the best temperature and 90C is too high and 50C too low.
