With great interest I read an article in Food & Wine magazine. About Kewpie brand Japanese mayonnaise, and why it’s an integral part of making this egg salad sandwich. And no, that’s not a lettuce leaf peeping out on the left, it’s the green measuring cup I used for the mayo. LOL.
A post from Carolyn. I have way too many recipes waiting to post – I must have 7-8 waiting to be written up and now this one. Ever since I handed over my gavel in PEO to a new president, I’ve had a lot more time on my hands. Good time. Time to read, to wind down the pile of magazines I have sitting in my family room, and time to cook. So, as I leafed through an issue of the magazine I stopped at this one, about a particular style of egg salad, from a 7-Eleven stores in Japan. The writer was on a mission of sorts – he’d spent some years in Japan and frequented a nearby store and often bought sandwiches there. He didn’t realize how much he loved them until he wasn’t living in Japan anymore. So he set about trying to recreate the sandwich.
I’m such a sucker for those kinds of stories, they just pull me in. I do love egg salad sandwiches and rarely eat them (since I try not to eat bread). I had some soft potato bread in the freezer. No, I didn’t have any of the specialty Japanese milk bread (although I have a local bakery that makes it and I love it), but the potato bread would suffice. But first, I had to find the Kewpie mayo. I could have taken a drive to a local Asian market about 7-8 miles away, but with the price of gasoline these days I opted to get it on amazon.
What’s different about this mayo? Well, having taken a little tiny taste of it, I’d say it’s a bit more acidic – maybe vinegar or more lemon juice. Since I WILL be making this egg salad mixture again in the future, I have some more Kewpie mayo to use. The recipe calls for 1/4 cup, so this little bottle will keep me stocked for several iterations. This recipe supposedly makes enough for ONE sandwich. Gee whiz. Five eggs (well, yolks plus half the whites) in one sandwich? I think it makes enough for two, and since I’ll be making them in half-sandwich portions from now on, I might make 2/3 of a recipe next time, so with three eggs. Or heck, make the full recipe and you’ll have enough for a couple of leftover servings.
Start off with some hard boiled eggs. I do mine in the instant pot, as I’ve mentioned here before, the 2-10-2 method (2 minutes on high pressure, 10 to cool down inside the Instant Pot, then 2 minutes in an ice bath). Keeping the eggs moist when you store them is also a key to success, to keep that membrane inside sort of wet – makes for easier peeling. I keep mine in a refrigerator container with a paper towel inside that stays very damp. Anyway, separate the eggs. All the yolks go in a bowl. The whites, well, you’ll only use half of them. And they need to be chopped up VERY fine. Mine weren’t done near finely enough, as you can see with the egg salad kind of seeping out of the sandwich up top.
Then to the yolks you add the mayo, salt, pepper and a little bit of sugar. Yes, sugar. It’s an important ingredient – the author said he knew his copycat recipe wasn’t quite right until someone suggested he add some sugar. That did it – he felt this recipe was spot on. One of the tricks to this is letting it rest in the frig for an hour. I didn’t have time to do that, and I think the mixture needs that resting time to firm up. Mine was too loose. After firming up you add in two teaspoons of heavy cream. Yes, really. Then the bread is spread with a thin film of butter, and the egg salad added. Close the sandwich carefully and also very gently slice with a serrated knife, cutting the sandwich in half. I’m just saying this sandwich for one, will serve two.
What’s GOOD: loved every mouthful of this sandwich, even though it oozed. It has a very smooth texture, nothing to distract you (like pickle relish or celery or onion, or even celery seed that I might ordinarily add). I LOVED this. And yes, I’ll be making it again. I might even try it when I next make deviled eggs. Do seek out the Kewpie mayo, though.
What’s NOT: only that you do need Kewpie mayo to make it authentically. And a nice, soft (not sweet) bread. Ideally the Japanese milk bread. Next time I will go buy some of the milk bread.

7-Eleven Egg Salad Sandwiches – Japanese
Recipe By: Food & Wine
Servings: 2
5 large eggs
1/4 cup Kewpie mayonnaise
1/2 teaspoon kosher salt — plus more to taste (use less if using table salt)
1/2 teaspoon granulated sugar
1/8 teaspoon black pepper
2 teaspoons heavy cream
1 tablespoon unsalted butter — softened
2 slices white bread — soft type, Japanese milk bread preferred
1. Bring a medium saucepan of water to a boil over medium-high. Using a slotted spoon, carefully lower eggs into boiling water; cook 11 minutes. Remove eggs using a slotted spoon, or carefully drain into a sink. Plunge eggs into a bowl filled with ice water, and let stand until cool, about 15 minutes. Drain well. Carefully peel eggs.
2. Using your hands, split eggs open; separate yolks and whites. Place yolks in a medium bowl, and mash using the back of a fork until broken down and a few chunks remain; set aside. Finely chop egg whites; place in a small bowl, and set aside.
3. Add mayonnaise, salt, sugar, and pepper to mashed yolks in bowl; gently stir until mixture is combined and some chunks remain. (Mixture should not be too chunky or a paste.)
4. Add half of the chopped egg whites to yolk mixture in medium bowl; reserve remaining egg whites for another use. Gently fold whites into yolk mixture until just coated. Chill 1 hour.
5. Stir cream into chilled egg mixture; season with additional salt to taste. Set aside. Spread butter evenly over one side of each bread slice. Top 1 slice, butter side up, with egg salad. Cover with remaining slice, butter side down. Trim off and discard crust; cut sandwich in half diagonally so you have 2 triangles. Serve.
