I’ve only leafed through Fiery Fermentation in the store, so I can’t say for certain. They have the steps of every recipe broken down very clearly into a 1-2-3 format. It doesn’t look like they have the large introduction that gets into all the full explanation in the way the Fermented Vegetables book does, but I think the Shockeys’ back-to-basics ethos makes fermentation easy to understand and practice even if you’ve never done it before.
I’ll also note that one of the my most successful ferments last summer was a hot pepper salsa from Fermented Vegetables, so they definitely know their hot stuff. I let it ferment the longest of any of my experiments, almost 3 months, and just like Chris and Kirsten said it would, it only got better as time passed. It enhances anything it touches, from salad dressing to collard greens to tuna to turkey burgers. My father, who has a real taste for heat and can take it better than anyone I know, ate it straight out of the jar. The brine turned green and became a hot sauce on its own. I take a gulp of it when I need to wake up or if I’m feeling peaky on a fast. It’s like a shot of adrenaline.
