I have a feeling thats why my pumpkin pie tastes so bad… sigh
Nope, they are completely different items. But you know that now. Sorry.
Nope.
Evaporated milk is exactly what it sounds like. Milk that has been gently heated and had some of its water evaporated out (it can be used as a substitute for regular milk by adding some water for recipes).
Sweetened condensed milk is slowly cooked with alot of sugar and is pretty thick stuff, to boot.
Don’t feel bad. It’s a common mistake (I even did it once a long, long time ago).
Did you know that if you make fudge with sweetened condensed milk instead of evaporated milk, you get this grainy, asphalt like substance that breaks your teeth when you try to eat it?
That’s how I found out that they’re different.
Strangely enough, my younger brother kept asking for “boo boo” fudge years after that little educational episode.
ya know… somebody really should tell this to the supermarket people that stocked it with the pumpkin pie filling. 
Luckily its just for me (and oh yes I WILL eat it) and it wasn’t baked for any special occasion.
Kinda has this too sweet burnt aftertaste to it though.
Haha! Your question reminded me of an experience I had many years ago. I wanted to make a daquiri pie (very tasty!), which required condensed milk. I put condensed milk on my shopping list, but couldn’t find it when I went to the grocery store. I looked and looked and looked; lots of evaporated milk, no condensed milk. I shrugged it off, and waited until the next week. Still no condensed milk. Anywhere. Finally, I tracked down a guy stocking shelves and asked him where the condensed milk was. “Right over there,” he said, pointing to a floor-to-ceiling display of evaporated milk. I looked again; half a dozen brands of evaporated milk; “evaporated, evaporated, evaporated …” I enumerated the products, “I need condensed.” “Isn’t it the same thing?” he asked. “NO” came a chorus of voices around us. He went to the back room and got me condensed milk. And the next week, there was a big end-aisle display and a special sale on condensed milk.
So, whammo, even the guy in charge of the canned milk stock didn’t know there was a difference. Apparently, your mistake is very common. Give that pie a go with evaporated milk. Yummy.
