How do I prevent chocolate top layer from falling off English toffee lower layer?
Making Chocolate English Toffe - Questions & Answers
After adding a top layer of chocolate onto cooled layer of toffee, it doesn't stick well and falls off when handled; how can I improve this bond between toffee and chocolate?
Someone else asked the question Why does the chocolate fall off of my homemade toffee?
some time ago.
One of the best suggestions was that you add the chocolate to the toffee while it is still hot. You don't even have to melt the chocolate first.
Just pour the hot toffee into the tray and then immediately place the chocolate pieces for the top layer on top of the toffee. The heat will melt the chocolate and allow you to spread it evenly.
Give that a try and let us know if it works for you.
