Untempered chocolate dries slowly, it does not harden fully and it has a dull blotchy finish. Many times it will have white streaks or spots called "bloom". Untempered chocolate has a soft and chalky mouth feel and it melts easily.

How long does it take for untempered chocolate to harden?

If the chocolate is in temper it will harden quite quickly (within 3 to 5 minutes) and become firm and shiny. If you touch it, your finger will come away clean.

Can untempered chocolate fix?

Stir solid vegetable shortening into the chocolate, using 1 tablespoon for every 6 ounces of chocolate. Mix gently and evenly until the chocolate has loosened and the shortening is incorporated. You can now use this chocolate for brownies, cakes, cookies, or other recipes that call for melted chocolate.
