Ethyl Tiglate is highly volatile and won't survive a pit environment. Once harnessed, it needs to be used and ideally in the spirit run somewhere rather than the wash.
I experimented with Dragon fruit skin and had one success and one failure.
The Dragon Fruit (Pitaya) I have the best access to is imported from Vietnam. It is not chemically treated, but thermally treated, so I left the fruit outside for three days to sequester S. Suaveolens from the environment. After the 3 days, I peeled the skin, discarded the fruit and added it to a mason jar with 1.5L of glucose solution (OG 1.040). The next day I added a Tbsp of boiled yeast and kept the jar at around 30C for 72Hrs. After that, I refrigerated it until I was ready.
S. Suaveolens is an alt-yeast in the form of a biofilm and that is precisely what formed on top of the surface of the liquid.
I made two identical small ferments of Molasses and inoculated one with the liquid from the top of the Dragon fruit (drawn with a pipette).
Both fermented out and I ran them both through my mini pot still. Compared to the control, the Dragon fruit inoculation was like an Apple brandy with a molasses finish. It was much more like a fruit brandy than a rum. Still very desirable though. Not fake apple in any way, it was crisp red apple and I'd love to have a big batch of it for blending.
My second attempt was a failure because I allowed it to go for 96hrs. It formed a spectacular mold colony with every colour of the rainbow and I had to toss it. Wish I had a photo of it. Was a disappointment, because I had also used a locally grown, organic Dragon Fruit.

I used a scoop of my garden dirt (potato bed) for my dunder. Who knows what all is in there...
Good judgement is the result of experience.
