AI have used this recipe many times and love it but I made a batch last night and it must not have been the correct temp when I combined everything because it has hard lumps throughout. I planned on covering the cake today and I know it is supposed to sit over night. I want to make another batch but does anyone know if it will be OK using it without letting it sit over night? I can let it sit for a couple of hours but cannot wait until tomorrow.

BUMP

no idea i'm sorry
 

AProbably little globs of gelatin that didn't get dissolved all the way. Either that of your ps had lunps? Anytime that's happened to me though, it was because the gelatin wasn't dissolved all the way.

AI agree, probably gelatin lumps. I never sift my PS but always strain my gelatin mixture.

Can you pick the lumps out?

You can use it right away, as long as you let it cool to lukewarm before you mix it into the powdered sugar. If it is too hot, it will sag and stretch off the cake. 

AThank you everyone. I think it was gelatin lumps. I had put the mixture in thr fridge to get it to lukewarm faster and I think that is where I went wrong. I made it again and let it sit at room temp this time and strained it twice before combining with the sugar. I wrapped it up and let it sit for 3-4 hours before I needed to get going. It worked just like usual although I did have to add a touch more glycerine. Thank you for your help everyone!

Can any of you share your MFF recipe??  I can't find it on CC after doing several searchs.  Thanks a bunch!!

AIt's just in my head after all these years.

Add 2tbsp gelatin to 1/2cup half and half, whisk vigorously, let sit until it's firm.

Microwave for about 45 seconds.

Whisk vigorously again, add a pinch of salt, 2 tbsp butter room temp, 1cup corn syrup, 2 tbsp glycerin, splash of almond extract. Mix like the dickens and if there's any chunks, strain, if not, into a KA bowl that has 2 lbs of ps in it, turn on low with dough hook.

Scrape down, add the other 2lbs of ps, mix, turn out to knead with a bit more ps. Wrap in lightly oiled saran wrap, and into a Ziplock bag.

Use next day.

ANow, that's how I do it. Is it word for word.the original recipe or the steps? Probly not. I'd look for it and follow along step by step your first.time out. On phone, so can't link you to it.

AExcuse the random periods...sorry. Google it, you'll find it.

Thank you, I did finally find one that I can follow using your measurements. There were several links to the recipe but the links didn't work. Thanks again.

Where can I buy glycerin?

went through a bunch of threads last week to find this recipe for Michelle Fosters Fondant.

AZcouture:  do you use this MFF with almond ext. on cookies?

regular fondant taste awful on cookies (no matter how nice they look)

AI don't make cookies, so I don't know. I'm sure it tastes fine though.
