To prepare the toffee, start by putting the milk in a saucepan with high edges: the mixture will in fact increase in volume
Add sugar 2 and mix cold.
Also add the vanilla essence and bring to the boil. Cook the mixture on a constant flame, stirring constantly 3 and being careful not to let it simmer.
As soon as the color appears golden, equip yourself with a cooking thermometer and monitor the temperature. When the latter has reached 120 °C, move the pot from the heat if you want to obtain soft toffee candies
Using a ladle, pour the mixture into silicone molds for chocolates and level everything with a spatula. Cool completely for 2-3 hours at room temperature (better to avoid the fridge).
Unmold the candies and wrap them individually inside sheets of parchment paper: the toffee candies are ready to be enjoyed
Notes
If you want to get some toffee from the classic square form, you can pour the milk and sugar mixture into a rectangular pan of about 24×20 cm (silicone or lined with parchment paper) and level it so that it has a thickness of 2 cm.When it’s cold enough, but still soft, just cut it into 2 cm squares or, alternatively, use small circular pastry rings.You can flavor candies according to your tastes: cinnamon, orange peel, coconut or pistachio grains, bitter cocoa powder are just a few ideas to try.Plus, if you don’t have to serve them to the kids, you can add a shot of witch liquor or rum.Finally, to make your toffee sweets really special, try sprinkling them with some coarse salt before serving: you will get a deliciously balanced taste between sweet and salty.
