Start with poppy seeds and a 1:1 syrup

Use an old teflon pan, it might not be fine after this

Use a lot of toothpicks tied together with a rubber band.

Every few hours, pour some syrup in the hot pan until it sizzles, then push the seeds through it. You can repeat this for maybe 3 times, but don't overdo it (you can meld the whole batch!).

Do this for a week or so.

I did a rhubarb one in spring, that was quite nice!
