Opened this and it didnt have any substance, just watery white liquid - put me off my food. Requested a refund. Will stick to other brands in future.

Received from Ocado to review. The squeezy bottle is handy and gives good portion control as well as being easy to apply. Theres a slight vinegar taste which makes for the perfect accompaniment to chips and burgers and made a very tasty egg mayo. For general use theres nothing not to like and I would buy again.

Gluten Free mayonnaise! Thank you. It tastes great. I like the squeezie bottle. No noticeable vinegar taste. Really pleased with this product.

Not that good

Bought on offer. A bit tasteless and bland. Plus I find the squeezy pack difficult to get the mayo out. of Will go back to Hellmans.

Tasteless

Got this as a freebie to review and I hate giving bad reviews but this was just ok and pretty tasteless. Mayonnaise is supposed to be eggy this was just a white lubricant,will stick with the other mayonnaise starts with H!

The best mayonnaise!

The best mayonnaise- great taste and consistency. Only drawback is it can be tricky to get the last bit out of the squeezy bottle

I received this for free from Ocado. Its extremely thick & creamy & quite addictive! Delicious with chips,salads & burgers. Highly recommended!

as good as it gets
22 January 2024

Its impossible to find a mayonnaise that has a great list of ingredients and tastes delicious. Ive been working through the different brands/versions. The flavour of this one suits me best so far, lost a star for ingredients. I will have to walk to Waitrose for the good stuff.
