If it ain't broke, don't fix it!!!
This used to be excellent until Tesco changed the source with a new recipe. It is now bland and tasteless. Original was made in Belgium..
Tastes ok if this is all you can buy. However it does not keep well in the fridge when opened.
AWFUL - new recipe
DO NOT BUY, they have changed the recipe and it is awful. I had an old jar and compared and the ingredients have changed a lot.
April 2020 recipe changed
I have been using Tesco seafood sauce in sandwiches and on salads for about 20 years. The recipe has been changed from having 47% rapeseed oil to now having 14%. The sauce is less thick than it was before and the main flavour that comes out is mustard. It doesn't taste much like the Marie Rose sauce it used to and this is a shame. I will have to switch to one of the other brands. I would have rated it 5 stars before it was changed
