I’m planning on making salted caramel tartlets. The recipe calls for melting soft salted caramels with cream. I haven’t been able to find salted caramels, but have regular caramels. I’m assuming I can make the tartlet with regular caramels as well, but do you think it’s possible to add salt to regular caramels when melting it to get to a substitute for salted caramels? And, if so, how much salt should I add?
