HOW THE HOLIDAY CAME TO BE

The month reached print years before the day did.

No founder or establishment record has been located in the indexes checked, and the day's name returns nothing in the Federal Register, in California's newspaper archive or in HathiTrust's full text. Its earliest archived third party listing was captured in May 2012, already headed 12 April, which dates the listing rather than the day.

INTRO

The cheese in it was a chemistry problem first

A California newspaper called the Big Pine Citizen printed a recipe on 13 July 1929 under the heading Grilled Cheese Sandwiches. It opened by telling readers to spread bread with butter. The sandwich at the center of National Grilled Cheese Sandwich Day already had the name it carries now.

The story that circulates about that name says nobody used it until the 1960s. The decade is right. The claim is not.

In Google Books' English corpus, grilled cheese sandwich moves ahead of toasted cheese sandwich in 1960 and stays ahead in every year through 2019. The 1960s are when the newer name won, not when it was coined.

ORIGINS

Grilled Cheese Sandwich Day history

INTRODUCTION

The problem starts with the cheese. A block of aged cheddar in a hot pan does not behave, and that was a manufacturing headache long before it was a lunch one.

James Lewis Kraft, of Chicago, filed a patent on it in March 1916 and had it granted that June. His method was blunt. Cut the cured cheese small, put it in a steam jacketed kettle, bring it to about 175 °F and keep it stirring throughout.

CHAPTER 01

What the Navy actually cooked

The Second World War is where the legend puts the sandwich's invention. The Cook Book of the United States Navy, issued in 1944, does carry a cheese recipe, scaled like almost every recipe in it to a hundred portions at a time.

It is headed American Cheese Filling. Ground American cheddar is stirred together with prepared mustard, chili sauce and mayonnaise until it is smooth. A note underneath tells the cook to spread the mixture on one slice of toast and put it under a broiler.

The words grilled cheese appear nowhere in the volume. Neither does toasted cheese.

CHAPTER 02

When it was toasted cheese

For decades the two names ran side by side, and the older one was ahead. In California print between 1900 and 1959, toasted cheese sandwich turns up 286 times against 201 for the grilled version.

The grilled hits cluster at the end of that run. One falls in the 1930s, fourteen in the 1940s and 186 in the 1950s.

CHAPTER 03

April fills up

The month is in print before the day is. A Ventura County Star story of 8 April 2001 describes the sandwich being honored during National Grilled Cheese Month, and it turns up again in a Dairy Farmers of America trade publication.

The day's full name is harder to find. It returns nothing in the Federal Register, nothing in California's newspaper archive and nothing in HathiTrust's full text, and nothing in those indexes names a founder. What can be dated is the listing rather than the day: the earliest archived third party listing was captured in May 2012, already headed 12 April.

TIMELINE

Timeline

Kraft patents a cheese that keeps

James Lewis Kraft's process heats and stirs Cheddar type cheese so it can be sealed and kept without breaking.

A California paper names the sandwich

The Big Pine Citizen prints a recipe headed Grilled Cheese Sandwiches in an article headed The Kitchen Cabinet.

The Navy prints its cheese filling

The Cook Book of the United States Navy carries American Cheese Filling on page 207, to be spread on toast and grilled.

Grilled moves ahead of toasted

In Google Books' English corpus the grilled name passes the toasted one and holds the lead through 2019.

The current standard is published

The rules that now govern pasteurized process cheese appear at 42 FR 14366, fixing the emulsifier list and the heat minimum.

A newspaper marks the month

The Ventura County Star reports the sandwich being honored during National Grilled Cheese Month in April.

GOOD TO KNOW

Surprising facts about National Grilled Cheese Sandwich Day

The FDA wrote a grilled cheese into its menu rules

The menu labeling regulation at 21 CFR 101.11 uses Grilled Cheese (Cheddar or Swiss) as its worked example of a menu item that comes in versions. Its illustration of a slash pair of calorie figures reads 450/500.

Labor rules use it to define light cooking

Explaining where it drew the line for 14 and 15 year olds under 29 CFR 570.34, the Department of Labor wrote that preparing an occasional hamburger or grilled cheese sandwich did not seem to place young workers at risk.

Thirteen salts are cleared for the job

The standard of identity for pasteurized process cheese names thirteen permitted emulsifying agents, all of them phosphates, citrates or tartrates. Their solids may not exceed 3 percent of the weight of the finished cheese.

The record sandwich weighed 418 lb 11 oz

Exodus and Iggy Chaudhry cooked a grilled cheese 10 ft 10.7 in long in Milwaukee on 21 October 2023. It took more than 88 lb of cheese, and the leftovers went to local food banks.

The name without the National is older than expected

HathiTrust's full text finds the phrase Grilled Cheese Sandwich Day in School Foodservice Journal for 1978 and for 1979. Both volumes are search only, so whether it named an observance or a cafeteria menu day cannot be read.

WHY THIS DAY MATTERS

Why We Love National Grilled Cheese Sandwich Day

CHEMISTRY

Take the calcium out and the protein lets go.

Emulsifying salts sequester calcium, which lowers the concentration of free calcium ions and breaks the casein micelles into small clusters. The proteins then take up water and disperse, which is how the fat stays evenly distributed instead of running out.

LAW

Process cheese has a federal recipe

Under 21 CFR 133.169 pasteurized process cheese is heated for not less than 30 seconds at a temperature of not less than 150 °F. The same section makes Pasteurized process American cheese a legal designation for process cheese made from cheddar, washed curd, colby or granular cheese, or any mixture of them.

SCHOOLS

It is written into school food rules

A 2000 National School Lunch Program rule works a portion counting example around a Tuesday menu of a hamburger, a turkey sandwich and a grilled cheese of one and a half ounces. When the saturated fat limit for snacks sold in schools was finalized in 2016, commenters argued it would exclude grilled cheese along with chicken tenders, hot dogs and pizza.

GET INVOLVED

How to Celebrate National Grilled Cheese Sandwich Day

EDITOR'S PICK

Cook one slowly in a buttered pan

Low heat gives the cheese time to go soft before the bread darkens. Butter both outsides and let it take its time.

COMPARE

Compare a processed slice against aged cheddar

Melt one of each in the same pan and watch what they do. The difference is the whole reason a federal standard exists.

ASK

Ask an older cook what they called it

Toasted cheese was the commoner name in print for decades. Somebody in your family may still use it.

SPLIT

Split one with somebody at the stove

Cut it corner to corner while the cheese is still moving. This is not a sandwich that improves on a plate while it waits.
