Make sure your chocolate is chopped (if need be) and all chocolate pieces are the same size. If you are using Mama Ganache Chocolates, then I usually don’t chop these more, the medallions that they come in are just fine for melting. But, if you want it to be quicker and smoother, then you can chop these too!
Add about 80% of your chocolate that you want to temper into a heat proof bowl. Set aside the remaining 20%. You can use your scale for this or you can eyeball, either way is fine.
Melt the 80% chocolate that is in the heatproof bowl using the double boiler method. Melt until the chocolate reaches 100°F degrees for white chocolate, 110°F degrees for milk chocolate, or 115°F degrees for dark chocolate. Remove from the heat immediately.
Slowly add in the remaining 20% of chocolate and vigorously stir to combine completely. Allow the chocolate to come down to 89°F temperature for white chocolate and milk chocolate, or 91°F temperatures for dark chocolate.
You can test to see if it's tempered by putting a small bit on a piece of parchment paper. Place it in the freezer to set. Remove it and let it come to room temperature. If it's glossy and snaps, then it's tempered.
Use the tempered chocolate in your recipe to coat candies or cookies.
