Kewpie (or QP) Mayonnaise has to be one of Japan's greatest inventions.
First made in 1925, Kewpie has a richer, creamier flavour than your usual mayonnaise due to its exclusive use of egg yolks and a mix of apple and malt vinegars. Use as a topping on any deep fried foods to balance the saltiness.
Each bottle is 500g, packaged in a convenient squeeze-tube.
