CMC Powder (tylose) can be added to fondant to make it into gumpaste. Simply add 2-3 tsp. tylose to 1 lb. of fondant. Knead it in and let it rest overnight.
CMC Powder (Tylose) is used as a substitute for vegetable gums in gumpaste. Tylose will add flexibility to gumpaste and fondant without adding color. Tylose holds up better than gum tragacanth in humidity and costs less. The following is a recipe for homemade gumpaste using tylose. The edible glue recipe that follows is great for attaching gumpaste pieces or gumpaste flowers.
CMC Powder (Tylose) Gumpaste
The following recipe will make approximately 2 pounds of gumpaste:
4 - Large Egg Whites
1 - 2 lb. bag 10x powdered sugar
12 - Level teaspoons CMC Powder (Available in our online store)
4 - Teaspoons shortening (Crisco)
1. Place the egg whites in a Kitchen Aid mixer bowl fitted with the flat paddle.
2. Turn the mixer on high speed for 10 seconds to break up the egg whites.
3. Reserve 1 cup of the powdered sugar and set aside.
4. Turn the mixer to the lowest speed and slowly add the remaining sugar. This will make a soft consistency royal icing.
5. Turn up the speed to setting 3 or 4 for about 2 minutes. During this time measure off the tylose into a small container.
6. Make sure the mixture is at the soft peak stage. It should look shiny, like meringue and the peaks fall over. (If coloring the entire batch, add the paste color at this stage, making it a shade darker than the desired color.)
7. Turn the mixer to the slow setting and sprinkle the Tylose in over a five second time period. Next, turn the speed up to the high setting for a few seconds. (This will thicken the mixture.
8. Scrape the mixture out of the bowl onto a work surface that has been sprinkled with some of the reserved 1 cup of
powdered sugar. Place the shortening on your hands and knead the paste, adding enough of the reserved powdered sugar to form a soft but not sticky dough. You can check by pinching with your fingers and they should come away clean. Place the finished paste in a zip-top bag, then place the bagged paste in a second bag and seal well.
9. Place in the refrigerator for 24 hours if possible before using to mature the paste.
10. Before use, remove from refrigerator and allow the paste to come to room temperature. Take a small amount of shortening on the end of your finger and knead this into the paste. If you are coloring the paste, add the paste color at this stage.
11. Always store the paste in the zip-top bags and return to the refrigerator when you are not using the paste. Will keep under refrigeration for approximately 6 months. You can keep the paste longer by freezing. Be sure to use zip-top freezer bags. If you will be freezing a batch of paste, allow it to mature for 24 hours in the refrigerator first before placing into the freezer.
Recipe for Edible Glue
1. Bring one cup of tap water to a rolling boil and remove from the heat.
2. Add 1/2 heaped teaspoon of Tylose powder to the water. Stir well with a fork to break up the Tylose. Allow to cool, stirring often to dissolve.
3. If necessary, place the mixture in the refrigerator overnight to allow the Tylose to dissolve.
4. Place in an airtight bottle when cool. Has a shelf life of approximately 30 to 60 days, but will keep longer if kept refrigerated when not in use.
