Easy to make and use Pastillage. This recipe is great for building 3d edible objects and architecture.
1 package of plain gelatin
1/2 cup water
1 teaspoon cream of tartar
5 cups powdered sugar (sifted)
1 cup cornstarch
Sift the powdered sugar and cornstarch together. In a small saucepan, place water and cream of tartar in, then sprinkle the plain gelatin over the top.
Stir over low heat until dissolved. There may be an amount of cream of tartar that doesn’t dissolve, just be sure no amount of gelatin is left undissolved.
Remove from heat and add to bowl of stand up mixer, like a Kitchen-Aid.
Put on a paddle attachment and with low speed, add in the dry ingredients mixing spoonful by mixing spoonful (couple of tablespoons at a time or so) at a time. When all is incorporated, switch to medium speed until mixture is lightened and very white, about 3 minutes.
Remove from bowl, wrap in plastic wrap and let sit for half an hour before rolling out.
Can be frozen; place in refrigerator overnight to thaw.
Roll out with cornstarch.
