Roughly chop 2/3 of the couverture. Place in a heatproof bowl over a pan of boiling water and melt until the desired temperature (55 °C dark/ 50 °C milk and white) Tip - it is better to do this very slowly so that the chocolate doesn't burn.
200 grams milk chocolate couverture
Take the bowl out of the water bath and add the remaining 1/3 of the couverture to the mix, piece by piece, stirring until Temp #2 has been reached. Don't worry, this phase always takes me a long time too. Reheat the chocolate slowly, until it has reached Temp#3 Now the couverture is ready to go into your chosen mould. Place it on top of a piece of cling film.
Slowly pour the chocolate over the mould, almost to every edge. Carefully knock it against the table/counter top to remove all the air bubbles. Turn it upside down, over the cling film, and let all the excess chocolate come out. Scrape the top clean with a spatula, and let everything set.
Water ganache time! Roughly chop the dark chocolate and put in a bowl with the salt. Pour the boiling water over the top and stir until the chocolate is melted and the mixture is smooth and shiny.
Whilst the ganache is still semi-fluid (it gets a. lot thicker with time), fill the chocolates to a little more as 2/3rds full.
Melt the remaining chocolate from the cling film (once it is hard, you should be able to simply pop it off) by using the desired tempering method again. Just a little bit more patience needed!
Pour again the tempered chocolate over the mould, so everything is covered. Then scrape the excess chocolate off (ideally with a dough scraper) so that each chocolate has a clean edge. Leave everything for at least an hour.
To take the chocolates out of the form, you need a bit of strength. Bang the form against a hard surface and all of them should fall out. If that doesn't happen, it sometimes helps to leave them 10 minutes (no longer) in the freezer
