No thermometer?
Needed a water temperature of 65°C for a scald but have no thermometer. What to do?

When I last did this recipe i came across the same issue but forgot till putting together the scald. Now I remember :)
It's not exact as a lot of things have to be considered but it's a good estimate. Boiled the water then left it to cool for 10 minutes.

Buy a thermometer! I have a Thermopen that was almost $100 and two from Amazon that were under $20 each. All are equally accurate but the Thermopen is faster and has a larger display.
But always remember when I'm half way through a recipe
Considering that room temperature is around 70F, and body temperature is 98.6F, I would think 65F water would feel quite cool to the touch, no?
The OP specified "65C", which is about 150F.
As a Canadian I'm a bit confused, as we use both Celcius and Farenheit for various things! Same way we mix Imperial and metric measurements. :)
In which case, 65F is hot enough to cause skin damage when exposed to it for more than a couple of minutes. So it should be too hot to stick your finger into for long! A cup of tea that's a bit too hot to drink yet. :)
I never realized how incongruous this was until I was posting on TFL. We measure mass in grams, but buy pounds of butter, we do Celcius for outside temperature but use Fahrenheit for oven temperatures, use imperial cups for volume but buy milk by the litre and so on. We have a foot in both worlds!?
Yes, it became clear to me years ago when I was doing a lot of sewing. I went to the fabric shop one day to buy 2 metres of 45" fabric. :)
That seems a bit cool for scalding...most people talking about heating until bubbles start to form at the edges of the pan. No thermometer needed.
