Line a baking tray with baking paper
Preheat oven to 180 degrees fan forced, and position rack into middle of oven
Place seeds and honey into a bowl and combine … be aware that it is going to be very sticky which is what you would expect with honey
Place mixture onto a baking tray, spreading it out as best as you can, then sprinkle over salt (although mix is sticky, try to get all the seeds out of the bowl and onto the tray … too good to waste)
Bake in the oven for 5 minutes
Remove tray from oven ... stir seeds around a little, which can be easily done now as the honey is hot, and position seeds so that they are more or less joined together in a square or rectangle … this will help with the final baking step
Return tray to the oven and bake for 5 minutes until golden
Remove tray from oven, set a timer for 5 minutes and allow mix to cool … this is important because if you try to do the next step whilst the seeds are still hot, the mix will stick to the back of the spoon making it difficult to spread out into a single even layer
Whilst the mix is cooling for 5 minutes, rub olive oil over the back of a largish metal spoon
Now use the back of the spoon to run over the warm seeds to level them out into a single thin even layer (because the seeds have cooled a little, and you have oil on the back of the spoon, they will not stick to the spoon)
Make sure you press down on the seeds as you run the spoon over the top … the more even they are the more even they will bake so that you don’t have one area thicker than the other … also try to maintain your square or rectangle shape as you should be able to use the back of the spoon to push stray seeds back into the pack whilst they are still warm
Return the tray to the oven for a further 5 to 6 minutes until a deep golden colour
Remove tray from oven and allow seeds to cool for about 30 minutes
As soon as they are cool, break the seeds into the size/shapes that you like and place into a sealed container in the fridge where they will keep for up to a month
You can use them as shards on top of the mousse, but you can also break them up and use them as a crunchy sprinkle on top of the mousse if you prefer
