In the notes, our esteemed BK included the following ingredients:
1 pound of large elbow macaroni
Mayonnaise (Best Foods ONLY)
1 can Bumble Bee all-white tuna in water (or any brand you like – but in water)
1 red onion
Silly BK probably doesn't remember that Best Foods is not sold as Best Foods east of the Rockies. On this side of the continental divide, it is known as Hellman's.
Yes, we sell Hellman's at the store.
But I've been known to make my own mayo. By hand.
It's simple: whisk an egg yolk with a whisk until it's nice and sunny yellow, add a little salt and vinegar (or lemon juice), and then ever so slowly whisk in a cup or so of oil, just a drop or three at a time at first, until everything is emulsified. (What kind of oil you use greatly affects the flavor of the mayo.)
Add some garlic to the mayo while you're whisking, and you've got aioli.
But stick with the Hellman's/Best Foods for BK's Tuna Pasta Salad recipe. They not only bring out the best, but they also have more air whipped into them, which alters the taste.
I'd whip in that much air, but my arm gets worn out too soon.
