Two-thirds of your chocolate over a bain-marie. Not a drop of water. Bring gently to 50°C — no higher.
Off the heat. Add the remaining third (chopped fine) as seed. Stir slowly and constantly. The temperature will fall.
Once you hit 28°C, warm gently to 31-32°C for dark, 29-30°C for milk, 28-29°C for white. This is the working window.
Spread a smear on baking paper. In 3 minutes it should be dry to the touch and glossy. If it's streaky, restart.
