Cake Central Top Picks
i would use crisped up fondant because it is more forgiving that pastillage--i crisp it up with added cornstarch--for example knead in a 1/4 to a 1/3 cup to a pound of fondant--adding tylose is also very popular for crisping up fondant
i like fondant because it has a forgiveness factor absent in pastillage~~
pack the rkt down real real tight in the general shape--just a bit bigger all over and let them set up overnight
then you can trim them --and you can get them super smooth with a microplane
rkt are good but they can require some support
the thicker the rkt the better it supports itself so i think you'll need this thinner in places or at least thinning out
so for an unbeatable substance depending on how thin you want it--you could whirl the rkt in a food processor then make the rkt out of that and pack that down nice & tight and it's very sturdy--would hold up under the fondant covering
but keep in mind you may need doweling too
maybe use a combination of both out-of-the-box krispies and food-processed krispies
i would love to see pictures if you feel you want the world to see your work
some cakes i can't wait for someone to hack them to bits with a machete so no pressure!!!
that is what i would do because i know i can get the fondant to cooperate with me
pastillage would work but it's not my first choice
modeling chocolate is another idea
so you need to use what is best for you ;)
if i was doing this i'd use store bought fondant right out of the bucket over the rkt
maybe knead in some shortening but no extra starch or sugar is how i would do it
but it doesn't matter how i would do it
in fact you need to do a little testing asap
make a little bit of everything asap and see how it handles for you
so you still have some time to scramble ;)
be prepared to perhaps black out the arches if necessary instead of cutting them ;)
you are biting off way too much in one week's time learning all these new things
i'm not saying it can't be done but dang wow it'd be too much for me if i hadn't started this a week ago
i'll help some more --i'm just freaking out some for you ;)
at least you don't have a full time job and going to school on top of the two kidlettes while catering meals on the side do you? :)
for all the arches--i'd make cookie cutters--so you have this drawn to scale do you???
how are you going to get the rkt molded???
possibly a more realistic way to approach this is to bake a two layer oval and make rkt* for the second tier which is the higher side of the colosseum
with all due dilligence to the proper doweling it needs to stand up there
and use black out for the arches and adorn around the arches with piping and fondant accents
you could do two layers of fondant-- one black then white on top and cut away the white to reveal the arches--but that's not for the timid nor for newbies either
like i said yes it is possible the way you said but oh my with all new substances to make correctly and perform to their fullest extent--possible but not likely
but the colloseum is in ruin so a low threshold there :) jk jk
*and you can use the empty cake pan to mold the rkt the shape you need
unless you already have a mold for that?
I've just spent the last 3 hours trying to draw the Colosseum to scale, and worked out that the walls would end up being 4" high!!! And that would be the higher one!! If I work it out using my arch cutter ( 2") the height of the cake would be 13" high!! I'm still hoping I can use the cutter as it will save me a lot of time!!
by my calculations your cake should be about a 25x15 ellipse and 7 inches tall give or take with 80 arches on each of three stories -- except for the ruins parts--if it was all intact that is
the arena in the middle should also be about 7" wide and maybe about 12" long for it to be to scale
but that's just my rough estimate
it was built at a 5-3 ratio and the height of the outside wall is the same as the width of the arena--the arena appears to be half the size of the width and length
so if there were 80 arches hmmm...
so the 1/4 of the perimeter of the ellipse i drew with those dimensions is approx 17" so i'd just do one arch every inch and fudge it a teeny bit or make the ellipse a tad bit bigger to be able to get one quarter of it to measure 20" and do one arch per inch so maybe a 27x17 ellipse give or take and increase the height of the outside wall and the arena to 8.5 inches
that's a ton of teensy arches
i mean i don't think anybody is going to be counting them up--i mean who even knew there were 80 in the first place?
but if you need to make them to scale with a 2" arch then it's gonna be way freaking huge
so for example with the 5:3 ratio if it's a 13" outside wall height which is the same for the size of the arena then the length & width of the ellipse is 44 x26
that's quite a large colosseum ahahahhahahaa
this is so out of control!!! ;)
