From time to time I find myself craving the food I had in Japan. Sometimes it’s the simplest of things, like this Japanese egg salad sandwich. Because even though you’d think there isn’t much wiggle room in how to make egg salad you’d be amazed what a difference a few little tweaks make. I think the biggest difference is that the egg is mashed, not chopped and the mayonnaise must by kewpie for a truly authentic taste. The pinch of salt adds that little je ne sais quoi that makes this run of the mill sandwich spectacularly moreish!
For one sandwich:
2 hard boiled eggs
2tbsp kewpie Japanese mayonnaise
Pinch of salt
Soft salted butter
Two slices white bread
– Put the eggs, mayonnaise and salt in a bowl and mash with a fork until there are no large chunks. You could even use a food processor to get it even smoother (some conbini do) but I prefer a little texture.
– Spread the bread with butter and add the egg mix. This should be a well filled sandwich! (Though factors such as egg size and bread size will affect it, you may find this makes two less well filed sandwiches if using smaller bread.)

Apart from the particular type of mayo, this is exactly how I’ve grown up with egg sandwiches way up in the Scottish highlands. Mashed with a fork with a pinch of salt, mayo and soft white bread and slightly salted butter. Another bread that’s amazing with it is a Scottish plain loaf.
Superb!
