AEver done this?

I usually use Michele's (inspiredbymichelle) ganache 2:1 or 3:1 ratios. My thought was to do a white chocolate ganache using eggnog instead of the cream. I am wanting to ganache a cake to be covered and decorated in fondant ( so no refrigeration or a day or 2.

What do you think?

Could you not just add the spices to the heavy cream instead?  I'd be leery of leaving it out with the actual eggnog.

AYeah I was just thinking about that. Any recommendation of amounts?

I'd start with whatever measure of heavy cream you need and add your spices a bit at a time till it tastes right. . . you'll want cloves, vanilla, cinnamon, rum and of course nutmeg.  With the white chocolate you won't need to add any sugar.  I'd make it a little stronger flavored than you want the end product to be, since the chocolate will dilute the end product.

ACool thanks,I assume rum extract won't seize the ganache?

Thanks again!

Try LorAnn eggnog candy oil flavour--it will work in ganache for sure.  A good rum extract can be premixed with the cream and then used without seizing.

I put extracts in the finished but still warm ganache and mix it through. No seizing issues.

Actually, I was thinking real rum, but extract should work too.  Just make sure you mix it into the cream.  If you add it directly to the chocolate it may very well sieze it, but mixed with the cream it shouldn't hurt it at all.

Real rum or other alcohol needs butter to be added to make it like cream.  In place of 3/4 cup cream, use 1/4 cup of butter and 1/2 cup of liquor.  

Sorry this doesn't work by weight because the alcohol weight varies with the sugar content.

I'm going to jump in a little late here with another question? Why would eggnog be more perishable than cream? They're both dairy products. Is it because of the eggs? Just curious.
 

Yes, because real eggnog contains real (usually uncooked) eggs

I just yesterday made a batch of white chocolate ganache & used Lorann candy oil as flavoring. No seizing worries and it came out great. Just added 3-4 drops to 16 oz.  heavy cream then poured over the chips (Guittard).

I kinda wonders about that.... Yeah I'll go with the flavoring of the cream... I really appriicate your help. Using real rum would be nice....sooo I might try that first, but still have loranns on hand just in case! Thanks guys!
