I strained the seeds out of my bought raspberry filling to use as "ketchup" for the burger cake I'm making for my nephew's birthday. I was wondering if it is possible to write with it like piping gel? I was going to write on the board not the cake itself.

as long as it is thick enough, should be easily done. Just need to have the right size tip (#3 or 4 i would think)

I think it might melt or get runny. I would test it first!

if it isn't thick enough....

put jam in small sauce pan and start to simmer it. can reduce it to desired thickness. just remember it will thicken even more as it cools.

if in a rush...
mix a TBS of cornstarch w/ about a 1/4 of water and add to jam. Bring to boil. Will noticeably thicken and will get even thicker on cooling. May get so thick you have to thin with water to get to writing consistency.

Wow Doug! You always have well researched answers!

or is it just plain old being old!?!?!? (the avatar would be more accurate with grey hair!)

Well...... Thanks for sharing your old brain with us! HA HA

Thanks a bunch!! I think it is probably thick enough or maybe a hair thinner than piping gel. I'll do some writing when I get home tonight and see how it turns out after a couple hours. If it doesn't work, I have red icing. The gel just looks more like ketchup!!

I was making some lemon curd the other day to use as filling on a cake...found myself wondering, too, if I could use it for writing...lol. It does set up, eventually, and is pretty sturdy, but I was too chicken to try it. Please let us know if the strained rasp. jam works out! I'd love to see the results, too.

it occured to me while driving home today that the jam will dry out after being piped and will be come stiff, if not down-right rubbery...much like those fruit roll-up strips. (after all the roll-ups are nothing more than a jam that's been dehydrated and then cut into strips)

But wouldn't that be ok if you're just writing on the board and not the cake? I'm not sure....unless it dries out to the point that it shrinks and/or loses its sheen? hmmmmm....I think I have to try this out..lol

I used the rasp filling last night to write on the board and squiggle over the "fries". Take a look in my photos. I imagine it is going to get rubbery and probably ick to try but I don't expect them to eat that part!! I figured it was just better than regular icing or using say real ketchup!!

maybe you won't eat it....but I bet the kids will. after all they do love those fruit roll ups.

i think kids are attracted to a food based on its "gross out the adults" factor. the more we are grossed out, the more they like it.

Never tried it, but I am interested in knowing the outcome.
