Remember, fudge is a crystalline
candy. For creamy fudge, you want a lot of small sugar crystals.
Heating the mixture to a high temperature
(112°C) and then letting it cool (to 43°C) makes a supersaturated
solution. Supersaturated means more sugar molecules are in solution
than the solution can hold. This is a very unstable time in the
fudge-making process. Supersaturated solutions are easily disturbed—stir
it one bit and you’ve allowed the sugar molecules (sucrose)
to find each other and hold on tight, forming big sugar crystals
that make for a grainy fudge. Blech.
In more complicated fudge recipes (that
call for cream, milk, and sugar separately) it’s important
to stir during the cooling process (43°C and dropping). Stirring
at this time produces thousands of little sugar crystals. It can
get a little tricky. That’s
why we chose the easy route. Because we used sweetened condensed
milk, we avoided the pesky problem of manually controlling sugar
crystal formation—stirring at precisely the right time, until
your arm falls off. We like to think of our fudge as “automatic”.
Of course, some people think this is not fudge and that we are cheating.
To that, we say, priorities! |
