That recipe isn’t classic
Tuna salad is easy
Onions
Celery
Both fairly but not finely copped....no way...they get lost ...you want a bit of crunch
Lemon
Mayo...Dukes....Hellman’s or best foods is u must
Sweet pickles.....critical.....relish or chopped and some juice
Salt and pepper
Maybe Dijon mustard .....cilantro no way even if I love cilantro
Pretty darn close to the recipe posted.
I am amazed by folks that just use tuna and mayo
WRONG!!!
