chocolate contains cocoa butter, sugar and cocoa solids.
the fats are melted at different temps and are unstable.
the sugar also melts at a different temp than the fats.
to stablize the mix you must melt the chocolate to not more than 122 f, cool 1/2 to 85 f and combine to 100 - 110 f.
this can be done by melting 3/4 of your chocolate to 120f, adding 1/4 of the remaining chocolate fine chop and mixing by hand with a wooden or rubber spatula no whipping or frothing needed.
this method is called seeding and is quite easy as tempering goes.
you may also table the chocolate by melting the chocolate to 120, pouring half onto a clean, cool marble and moving it about with an off set spatula and adding back to warm chocolate when it begins to thicken.
the chocolate should feel slightly cool to your lower lip or the flesh on your knucle.
you can tell if the chocolate is ready by dipping a clean palate knife into the chocolate and set it down in a cool place, if the choc becomes dry and has a beautiful sheen, good to go.
this is a technique and must be done many times to do with ease.
