Fudge cooking question

Cafe Society
1

I have a recipe for peanut butter fudge. I need to boil sugar and milk to the soft ball stage.

Can I cook this in the top of a double boiler? Will it get hot enough? Or do I need to cook it in a pan directly over the fire(I have a gas stove)

Softball stage is 235° and your double boiler would struggle to get near 200 or so. Right on the gas is going to be required.

Thanks, I wasn’t sure.
