We reached all the way back to the “Mad Men” era for inspiration as we crafted this classic July Fourth side dish. It’s macaroni salad in all its tangy, comfortingly mayonnaise-rich, decades-ago glory.

This is pasta salad as your parents — or more likely your grandparents — remember it. You won’t be able to stop shoveling it onto your plate.

Want to make it more substantial?

Shredded cooked chicken would be a fine addition, as would cooked and crumbled bacon.

Or go for broke and add both. But whatever you do, don’t skimp on the mayo, and don’t even think about use light, fat-free or tofu mayo.
