Loved it

Loved it. Had already tried the green peppercorn and brandy with eye fillet which we also loved. Air fryer pork belly with the orange star anise was also very enjoyable for a change.

Hamburger flavour explosion

For something different I made a hamburger with fried onion, lettuce and home grown tomatoes and tried the Diane sauce instead of BBQ sauce, wow, what a flavour explosion. Definitely will be doing that again.

I’m known to make a mean Diane sauce, but this magnificence in a jar is next level taste! Devoured it on a perfectly cooked steak and used it to dip hot chips into. What a bloody ripper!

I read reviews before purchasing this sauce & decided on the Diane with leek. It was delicious. Bought 3 jars & gave one to my grandson who loved it so much put it on everything on his plate. Will definitely buy other varieties to try.

hi Regan and Dan, your source is amazing It is

hi Regan and Dan, your source is amazing It is so mouthwatering. The taste is a bomb. I just love it and my partner loves it too and he’s a fussy fussy person the other night he actually asked for it. I was really surprised we had it on scotch fillet steak but it never fails every bite you take you just get that beautiful creamy taste and makes your steak melt in your mouth. Say thank you. You guys are amazing. I’m so pleased that you sell it online cause you would never find that in the shop with the big stores anyway keep up the great work. I’m looking forward to doing more business with you in any future. Ns juliean p
