Honey doesn't need to be processed, just toss it in at the end of the boil. You can immerse the jar in a pot of boiled water to warm the honey and make it more liquid if necessary. Use rice syrup, not rice flakes. It'll be easier and you won't taste the difference. Pectinase is worth adding if you want a haze-free beer, but if you don't mind the haze, it's no big deal.
