Thanksgiving Ranch Bustard’s Mustard (250 mL) is handmade at the Thanksgiving Ranch using their now-famous family recipe. It was first used in their family bakery in the mid-1970s, initially created for special-occasion meals like Easter. It got a LOT of feedback from guests on their ranch. Namely, no one had tasted anything like this sweet and mildly spicy mustard and they wanted more! It is the only mustard known to them that has been known to cause addictive behaviours.
