Method
Add butter, glucose, and orange into a pan and gently warm until combined. Sieve the flour and icing sugar and add it to the orange mix. Add sesame seeds and place in a bowl. Allow to rest for 1 hour.
Preheat an oven to 180c. Once cooled, use 2 slip mats (or greaseproof paper if you don’t have these). Place the mix onto one of the sheets, then place the other sheet on top and use a rolling pin to roll flat. Once rolled out, place in the oven for 12 minutes. Take out and allow to cool slightly before removing the top piece of greaseproof paper. Leave to fully cool and then break into desired pieces and put in an airtight container for up to 1 month.
If you want to save time then you can buy sesame snaps from the supermarket and will work in a similar way.
