May have been answered somewhere on here so sorry, couldn''t find, but if you are using some lace molds with mexican gumpaste, can you do this ahead of time and would the lace remain soft and pliable to be able to place on the cake???   Thanks .....

Please give the list of ingredients or recipe link for this paste.

We cannot possibly give you a correct answer until you let us know.

Of course, sorry!!!  Ingredients:  Confx sugar, gum tragacanth and water.  Thanks...

I'm afraid that this will start to harden quickly. 

If you can leave it in the mold with plastic wrap tight to the back, you might be able to hold it for a day, but then you have tied up your mold.

If you are going to place lace onto the side of the cake, just let the pieces dry on the outside of the cake pan.  Then they will fit just fine onto your cake.  That way you can make a bunch of them at a time.

Mexican paste is like a poor man's pastillage.  It's designed to dry very hard, very quickly, so it must be worked with quickly. 

Thanks for the answers, great idea to do around cake pans...That's perfect..  As always best advice on CC....
