Molasses Sponge Toffee (GF)

Molasses Sponge Toffee – Gluten Free

February 12, 2017

Molasses Sponge Toffee is for fun loving people who enjoy getting a reaction out of common kitchen ingredients. The action between sour vinegar and baking soda heave this bubbly lava into billowy foam. When the foam cools, the bubbles and air pockets are trapped. Bite into this crispy candy and feel it melt into a sticky toffee. Also known as seafoam candy, honeycomb, or angel candy, this recipe uses dark and spicy molasses for an old-fashioned feel. Fair warning, Molasses Sponge Toffee produces excessive dribble, so best not to bring this special treat along on a first date.

Many thanks to King Arthur Flour for their great recipe. Check out their post on baking with molasses.
