How do they make the malted ketchup in Rose & Crown? so yummy

I love Heinz ketchup, but that malted ketchup was awesome. I was in Niagara Falls a few years ago in a small pub and they also had amazing ketchup tasted way better then the States has. I assume this is a British thing.

Anyone know how they make it or where could one buy it?

Do they use Malt Vinegar instead of cider vinegar in the manufacturing process?


I know even Heinz has different recopies for Ketchup for each country
