My Chocolate-Covered Honeycomb recipe makes crisp, airy candy with just 4 ingredients—no candy thermometer needed for homemade Crunchie bars.
Line a baking tray with parchment paper and set aside.
In a heavy bottomed saucepan over medium-low heat, let the sugar and golden syrup(or dark corn syrup) mixture melt gently.
Turn up the heat to medium and let it simmer until the color of maple syrup, about 3 minutes. Watch carefully so it doesn't smoke.
Turn off the heat and immediately whisk in the bicarbonate of soda fast and stand back and watch the syrup turn into a thick foam. Quickly stop whisking and use your spatula to pour this immediately onto a piece of baking parchment, or a Silpat sheet.
Leave until set cold and then break it up into shards, it will look like aerated set honey. To wash your pot fill it with hot water and let it sit and it will melt away.
To make a Crunchie Bar: Melt good quality chocolate (I used chocolate with 72% cocoa solids). Dip your broken honeycomb in the chocolate using a fork. Take out and let excess chocolate drip off. Place on a wire rack to set.
Note: This is a recipe used widely around the world for many years and with many names such a Cinder Toffee in Wales, Hokey Pokey in the UK, Sea Foam, Fairy Candy, Molasses Puffs, and no doubt other names I am not familiar with.
