Wait a sec dp ... I may have misunderstood your original post from today: Are you leaving the element off after you've turned it off? I presumed that you turned off the element with 15 mins left in the boil only for a minute or so while adding lactose, and then you turned the element back on again. That I wouldn't recommend as the lactose can settle on and coat the heating element and then possibly scorch when you turn the element back on. Best to just keep the wort moving with the element on the whole time.

If you're whirlpooling in the last 15 mins or so that would keep the wort moving so less likely to cause issues of course.

I'm not the best at explaining things..lol

I turn the whirlpool on at 20 mins left. That kills the boil because of the heat transfer going through the CFC. I then turn off the element and add the lactose. The pump is still whirlpooling. After everything looks dissolved I turn the element back on. This time at 100% to get back to a boil quickly. I tend to keep it at the 100% the rest of the boil to offset the few mins the boil died.

That should certainly work. As long as most is dissolved before you turn the element on there's no chance in scorching. I don't turn anything off myself, and instead just turn up the heat to 100% if adding a lot, and I always add slowly.

Some examples:

Adding ~1 lb of lactose to my Electric Creamsicle: https://www.instagram.com/p/CA3TVLrn4Ma/
Adding ~5 lbs of D-180 candi syrup to a Quad: https://www.instagram.com/p/CKcXWgJnxfY/
