Line a 23cm square baking tin or baking tray with non-stick baking paper. This is for the honeycomb which will be very hot, so make sure it is on a surface that can handle heat in case of any spills.
Next, take a large pan (the honeycomb mix will froth up a lot so choose a pan larger than you think) and add the golden syrup. Place over a gentle heat for about 1 minute - or until the syrup becomes very runny.
Add the sugar and bring to the boil, swirling the pan to stop it from burning (don’t stir). Once boiling, continue to cook for 3 minutes, swirling often to prevent it from burning. Do time it and don't guess.
Remove from the heat and shoot in the bicarbonate of soda. Stir quickly and confidently - you don’t want to overmix it but you do want it to be completely dissolved. Take care, it will really froth up.
Pour into the prepared tin/onto the prepared baking sheet and leave for about 1 hour - or until set. Don’t touch it at all during this time as it will be VERY hot. See the tips for how to clean your pan immediately!
Once the honeycomb has completely cooled, roughly chop into small-ish pieces.
Next, line a 900g / 2lb loaf tin with cling film, ensuring you have enough overhanging the sides. Set aside.
Pour the cream into a large mixing bowl and, using an electric whisk, whisk until you have soft peaks.
Add the condensed milk and whisk again until thickened.
Fold in the homemade honeycomb chunks until evenly distributed throughout.
Pour into the prepared tin and smooth over the top using a spatula. Cover with cling film and freeze for at least 6 hours.
Remove from the freezer 5 minutes before serving. Enjoy!
