I'm under the impression that UJ's are a special product not sold elsewhere.
I wholeheartedly endorse his links. I will never be able to say I've tried them all, but for the past few years, I buy a box of his links, and I never really go wanting.
Moo and Oink TURKEY hot links are something special, imo. Love those things too. You can get em at Moo and oinks, I usually get mine at Ultra Foods. The TURKEY ones. I've not bought the other ones with the Moo and Oink label. A family member turned me on to the TURKEY ones. They are flippin fantastic.
I like both of these because they have a balanced, sagey flavor, they're not overpowered by salt, and they have a decent kick of heat. Sausages are ususally salt overload for me, but I can (and sometimes do) eat these links all day long.
So, if you want the UJ's, just call them up, and ask if he can have a box ready for you. I think it's a 15lb or a 30 lb, they'll let you know. They will be frozen.
We cannot be friends if you do not know the difference between Mayo and Miracle Whip.
