Crabapple jelly and hard cider are primo uses. They also are prolific flowering trees and, as such, provide several functions with other Rose family fruiting shrubs/trees or fruiting plants that share similar bloom times - they bring in the pollinators in droves.
Litehouse is based out this way in Sandpoint, Idaho (about 50 minutes form my farm). I actually much prefer Toby's Blue Cheese dressing. If you haven't tried it, just hands down a better more robust Blue Cheese dressing - you should try it and let me know what you think. If you can't get it near you, I'll send you some. Seriously, it's that worth it.
Flavortown Secret Sauce? Never heard of it. Excited to try it! I'll see if I can find it before this weekend and report back.
