there are probably more recipes for eggs than you could possibly imagine but +1 on the boil. with my hens putting down so many eggs I've been able to tinker a little bit with what goes in but I keep going back to my favorite- sliced red onion in the bottom of a gal. glass jar, cider vinegar, garlic,pickling spices, black pepper to a boil, and let them set for about 2 weeks in the fridge before digging in( yea, right) haven't tried any mustard but will on my next batch
