1-Gather Your Ingredients and Tools: Start how to make chocolate ganache right with mise en place. Finely chop 8 ounces of chocolate into even pieces, about 1/4-inch, for quick melting. Place in a medium heatproof bowl. Measure 8 ounces heavy cream in a microwave-safe bowl or small saucepan. Have vanilla and salt ready. Tools: whisk, spatula, and thermometer if available. This prep takes 5 minutes and prevents rushed mistakes.

2-Heat the Cream Gently: Second Step: Warm the cream to create the emulsion. In microwave: heat on medium power in 30-second bursts, stirring between, until steaming and tiny bubbles form around edges (about 160°F/71°C, 1-2 minutes total). On stovetop: simmer over low heat, stirring often. Do not boil, as it can curdle or seize chocolate. Hot cream melts chocolate evenly without direct heat, key for smooth results.

3-Combine and Rest: Third Step: Pour hot cream over chopped chocolate. Let sit undisturbed for 2-3 minutes. Cream’s heat softens chocolate fully. Cover bowl with plate to trap steam if needed. Patience here builds perfect ganache; rushing leads to lumps.

4-Stir to Emulsify: Fourth Step: Stir gently from center outward with spatula. Use figure-eight motion, avoiding whisk at first to prevent air bubbles. Continue until fully melted and glossy, 1-2 minutes. Add vanilla and salt now, stirring in. If streaks remain, rest 1 minute more and stir. This creates stable dark chocolate ganache or milk version based on your choice.

5-Cool and Set: Fifth Step: Cool at room temperature for 30-60 minutes, stirring occasionally. For glaze, use at 90-100°F (32-38°C). Refrigerate 1-2 hours for frosting, then whip with beaters for fluff. Test consistency: pourable for drips, spreadable for frosting.

6-Final Step: Apply and Serve Pour over chilled cakes for drip effect, starting at center and tilting. Spread on sides with offset spatula. Let set 15-30 minutes. Yields 2 cups, enough for 9-inch cake. Store extras airtight. Troubleshooting: if split, add 1 tsp hot water and blend.
