so I always make MMF, but no matter how much of icing sugar I add its still not enough for me to make figures, I do have dried egg white powder and cream of tartar though, is it possible to add them in anyway to the MMF to make it into a modeling paste? please answer me ASAP as I'm gonna need to start my work in about 12 hours, Thank you!

Easy Pastillage [Modelling material]
1 package of plain gelatin [3 ts]
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 doesnt 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.
Drys quickly - dries hard ..

I'll try this now, Thank you so much!!
