You can scarify in various ways. Because these seeds were large and easy to handle I just held them and used a small kitchen knife to scrape away a bit of the outer coating.
The hot water bath is a step I have used before for these seeds and is often used for seeds with a hard seed coat or that resist taking up water. Because they were scarified first, these should soak up water fairly easily.
After I scarified the seeds, I put them in cups and poured hot water over them. I will leave them that way overnight and maybe through the day tomorrow, depending on how busy I am, but I will have removed them from the water by tomorrow night and wintersown half. The other half I will put in a little sphagnum in a baggie and stick them in the fridge.
People who germinate a lot of seeds develop their own preferred methods. That's part of the fun, imho.
