No...they're not Kosher. Not yet, at least. Here's where you come in:
I have emailed the company a few times over the past few years requesting they consider getting Kosher certification. Most recently, Vicki at the company said she's collecting requests for going Kosher, and will pass them on to the owner of the company.
If you've ever had their dressings, you know how good they are. If you keep strictly Kosher then you don't know, but I must say they are some of the best bottled dressings out there. Many of their ingredients are already Kosher, so it's a matter now of getting certification in their factories.
If this interests you, please email email@example.com with your request. Maybe us hounds can convince them to get certification.
