It looks amazing, right? Roasted marshmallows with Kahlua - why didn't anyone think of this earlier?
I'll tell you why.
a.) They are thoroughly disgusting. Seriously, they taste bad. Really bad. Have you ever had a cold roasted marshmallow? Of course not! They're not meant to be eaten cold!
b.) They're not that easy to make - you'll probably poke a hole in the side or bottom of the marshmallow so you won't be about to pour in the Kahlua.
c.) If you're roasting marshmallows over a fire, there's no way you're going to be able to see what you're doing well enough not to screw this up.
Let me explain...
If you roast marshmallows too quickly, the insides won't be gooey enough. You really need the insides to be thoroughly done, otherwise when you try to scoop it out, it'll either clump up and you won't be able to get any out, no matter how hard you try...
...or you'll result in having to stick your finger inside the marshmallow, which will be very sticky.
So here's what I recommend: get your marshmallows thoroughly cooked on the inside and don't wait for them to cool before making your hole with whatever the marshmallow was cooking on (your stick, knife, etc.). If you wait until the middle has cooled, it'll be harder to scoop out the insides.
Be very careful when scooping out the inside, as you can easily poke a hole in the side or the bottom of the marshmallow. I accidentally made a hole 3 out of 4 times.
If you're lucky enough to have your marshmallow intact, you can pour in your Kahlua but I'm warning you, it'll taste pretty bad...
...and there will be a hole in the bottom. Probably.
So are they feasible? Yes. Are they worth making on a camping trip? Well, you're probably better off roasting your marshmallow in one hand and drinking your Kahlua in the other. Combining the two just isn't worth it.
TOTAL COSTS: About $20
$1.67 for a bag of marshmallows from Vons
$16.50 for Kahlua from Bevmo
TOTAL AMOUNT OF TIME: Less than 5 minutes
This is assuming you roast the marshmallow in a minute and don't wait for it to cool before scooping out the middle.
EASY-PEASY SCALE (1 super easy - 5 very difficult): 4 out of 5
This is extremely difficult to do without making a mistake but I was able to get 1 out of 4 to work so at least there's a 25% chance of doing it correctly! The question is: is it worth it?
