I have recently tried to make fondant, the old fashioned way, with sugar, water and cream of tartar.
the final result, looked perfect, and if warmed it would make a perfect pouring fondant for cupcakes,and petit fours. But I need the fondant to cover a cake and mold a few characters. I did try adding Sodium carboxymethycellulose, though it did not make any difference. The fondant, was too soft, and sticky, and cracked when I rolled it out.

I know, i should just buy a tub from Crumbs, which i will most probably do in the end. though its worth a try.

I would appreciate and advice !

Hi there, I have made my own fondant a couple of times, and the recipe I use is this: 16 oz marshmallows (from the American shop), 71/2 cups of icing sugar, 4 tablespoons of water, plus any flavouring you want to add. If you have a stand alone mixer (i.e. Kitchenaid, Kenwood) just put everything into the bowl, having greased the dough hook and bowl before hand with shortening (Crisco, also from American shop). Apparently you can also do this in a food processor but I think the quantitiy would have to be halved). Use recently boiled water so its quite hot, turn on machine and just watch a huge mess turn into fondant. It takes a while, but the heat of the machine melts the marshmallows and it will come together into a ball of fondant. If it seems a bit sticky, just add a bit more icing sugar. When it has come together, just turn it out onto a greased worktop and knead it (adding more sugar if its a bit sticky). It should yield about 1.3 kgs of fondant. Good luck! Don't hesitate to ask any questions.

Thanks, I also made Marshmallow fondant, its fabulous. But the cake I'm baking is for a strict vegetarian, so not gelatin.

I made a batch with Agar Agar today, now its resting, I hope it works
