Step 7: Extra steps
Peanuts - worked pretty well as a crunchy, crispy peanut brittle.
Cinnamon - I added half a teaspoon of cinnamon along with the soda and it worked quite well, gave a bit of heat and spice.
Ground ginger - Much like the cinnamon, heat and spice which tingled nicely.
Cocoa powder - Didn't work so well. I was hoping for a chocolate honeycomb, but I think the fine cocoa ruined the structure and it kinda collapsed.
Chocolate coating - Much more effective, just melt some chocolate, let it cool a bit and drizzle over the chunks.
All lovely treats, easy and simple to make and quite impressive. Enjoy!
