  1. Butter a 20cm square tin.

  2. Mix 200g caster sugar and 5 tbsp golden syrup in a deep saucepan and stir over a gentle heat until the sugar has melted. Try not to let the mixture bubble until the sugar grains have disappeared. 

  3. Once completely melted, turn up the heat a little and simmer until you have an amber coloured caramel (this won’t take long), then as quickly as you can turn off the heat, tip in 2 tsp bicarbonate of soda and beat in with a wooden spoon until it has all disappeared and the mixture is foaming. Scrape into the tin immediately but be careful as the mixture will be very hot.

  4. The mixture will continue bubbling in the tin, simply leave it and in about 1 hr - 1 hr 30 mins the honeycomb will be hard and ready to crumble or snap into chunks.

Works everytime. I use a sugar thermometer and get it to 140.

Horrible! Loki's comments below are bang on. This is rubbish, I expect better from Good Food!

The first time I made this I think I took the sugar to far and some of the honeycomb tasted burnt. Tried again this morning and it looks good. I would agree on a previous comment about the colour, temperature would be better. Easy to clean if you soak I will definitely be making this again.

This ended up like lumps of toffee! It was very nice though but quite hard to eat...

Terrible! This recipe uses far too much bicarbonate of soda and makes the honeycomb taste like, well bicarbonate of soda. There are way better recipes elsewhere. If you're making this then I suggest using a quarter of the suggested amount of bicarb. Really disappointing recipe, results went in bin.

Great recipe, first time worked brilliant and was so impressed I tried to make double batch, this ended up being caramel, third time of single batch another success. No thermometer needed, just be patient and wait for the amber colour.

Only worked when I bought a sugar thermometer and left it until it was ‘hard crack’.

THIS RECIPE IS BAD!!! i followed to the word and my honeycomb came out like a sticky pancake. It was very malleable and overall i am very disappointed. My advice to you all would be to just buy a crunchie SO MUCH EASIER!!!!!! -Maisie xx

This worked for me BUT You must use a sugar thermometer to ensure you reach the right temperature without overdoing it and burning! It can ruin very quickly. The slowish dissolving of the sugar and constant gentle stir at the start is also important. Work fast once the bicarb is added. It makes lovely honeycomb ... and extra nice if you add melted dark chocolate once the honeycomb has set in the tin. Then once the chocolate has set - tip out of the tin and break into shards. yummy. Makes great gifts.

Tried this twice. Didn’t realise once on heat you shouldn’t stir. Also had it on such a. Low heat I was stirring solid for an hour with out it melting. Then it suddenly burnt. Both times. Tried Nigella’s recipe - perfect first time and ready in 10 minutes.

Can I use baking powder instead of bicarbonate of soda?

Thanks for your question. You do need to use bicarbonate of soda to create the bubbling honeycomb effect in this recipe.

Can I use a silicone used for baking instead of a tin? I use a lot of silicone things when baking.

Thanks for your question. Silicone bakeware can take exposure to high heat so it should be fine to use it in this recipe.

Thanks. This will be my first time making honeycomb. I haven't tasted honeycomb until Halloween of this year. IT WAS AMAZING!! LOL.

"Amber coloured" seems quite vague for something so sensitive; obviously a good few people are not really sure about this (including me!). What temperature should it get to before adding the bicarb?

Thanks for your question. The temperature can be between 145 and 150C. At 145C it will be more chewy, 150C will be more brittle. Hope that helps!

How long would the honey comb keep for? I'm thinking this would be a great Christmas present but not sure it will keep if i make it too far in advance!

Hi there, yes it will keep in an airtight container for up to one week - cellophane bags would be fine. If you're looking for something you could make sooner, take a look at our edible gift recipe collection. We hope you find something you like!

This is an amazing recipe for anyone. If you do not have a candy thermometer that is okay I make fudge, toffee and Carmel without one just get a bowl of cold water and drop a tiny bit of the toffee into it, it should become brittle quickly This shows it is ready for the bicarbonate soda. you can also do this to check how much sugar has dissolved.

I find it is not best to make this on a warm day because the honeycomb will absorb the moisture in the air, making a chewy toffee rather than a crisp honeycomb. Instead save this recipe for when it is slightly chillier out, or if you're in a cold room
