Origin of a Dish: Liquid Nitrogen Ice Cream

Liquid Air boiling on a block of ice. “If a kettle containing liquid air be placed on a block of ice, boiling will again take place and the addition of ice to the contents of the kettle will make the boiling proceed more rapidly.”—(Charles Leonard-Stuart, 1911) (source)

In 1987, a microbiologist in Lexington, KY, got the idea to flash freeze ice cream with liquid nitrogen, a chemical he was familiar with from working in his lab.  This was the start of the “ice cream of the future,” Dippin’ Dots, which is frozen by spraying ice cream mix into cyrogenic freezer. You can see a cool video of how it works here.

One would think using liquid nitrogen to freeze ice cream was a modern discovery.   But 86 years before Dippin’ Dots, British cookbook author Agnes Marshall, known as the Queen of Ice Cream, proposed the use of “liquid air” to freeze ice cream.

“Liquid air will do wonderful things, but as a table adjunct its powers are astonishing, and persons scientifically inclined may perhaps like to amuse and instruct their friends as well as feed them when they invite them to the house. By the aid of liquid oxygen, for example, each guest at a dinner party may make his or her ice cream at the table by simply stirring with a spoon the ingredients of ice cream to which a few drops of liquid air has been added by the servant.” –The Table (August 24, 1901)

I haven’t been able to find the primarily source article, but this quote comes from Mrs Marshall, The Greatest Victorian Ice Cream Maker, With a Facsimile of the Book of Ices, 1885 by Robert Weir.

Agnes Marshall, ice cream hottie.

“Liquid air” would be liquid oxygen, and I’m not sure if that’s what she actually proposed using, or if she was confusing it with liquid nitrogen.  The technology required to manufacture liquid air had been pioneered at this time, and there were presentations being done with it around the world.  Some reports say she demonstrated her ice cream freezing technique at the Royal Institution in London in 1904.

The technique went relatively untouched for the next century.  In the mid 1990s, the use of liquid nitrogen in the kitchen was further developed by Herve This, a chemist and cook who is known as the Father of Molecular Gastronomy.  Liquid nitrogen freezes ice cream almost instantly.  The faster ice cream freezes, the smaller the ice crystals; the smaller the ice crystals, the smoother the ice cream.  Ice cream made in this style was popularized by Ferran Adria and Heston Blumenthal, both considered pioneers of the molecular gastronomy movement.  Today, Top Chef contestants use it every other week.

Origin of a Dish: Vanilla Ice Cream

Sage and rosewater ice cream.

In the age-old question vanilla vs. chocolate, chocolate is the older ice cream, but vanilla has been the most popular ice cream of the last 200 years.

Ice cream as we know it descended from the European tradition of  dessert custards made with eggs.   The base for a “custard style” ice cream, or one with egg yolks in it, is the same as that for a baked custard.  So after the freezing process was discovered, it was a natural progression to frozen creams.  Some of the more interesting flavors from Medieval Europe include: saffron, honey & citron, sage & rose-water, laurel leaves, tarragon, celery, and crumbled cookies.

Vanilla was very hard to acquire before the mid-19th century.  It was only produced in Mexico, because of the vanilla orchid’s symbiotic relationship with the local bee–the bee pollinated the flowers.  Instead of vanilla, early ice creams were flavored with orange flower water or rosewater, ingredients commonly used in all sorts of desserts.

The first known written recipe for ice cream is from 1665,  handwritten in the recipe book of Lady Anne Fanshawe.  Notice she flavors her “icy cream” with mace, orange flower water, or ambergris (a ball of smelly brown stuff that whales puke up (ew)).  There’s a great article by culinary historian Ivan Day, who made ice cream from this recipe, here.

The first known ice cream recipe.

Vanilla doesn’t appear in ice cream recipes until the 1760s, and then it would have been used very rarely.  But Vanilla had been a favorite ice cream flavor even before the spice was readily available: there are about a dozen recipes in Thomas Jefferson’s papers, and one of them is for vanilla ice cream (see it here).  The earliest ice cream recipes published in American, in The Virginia Housewife in 1824, includes vanilla as well as almond, coconut, citron, and fresh fruit flavors (see it here, buy it here).   By the early 19th century, it was described as one of the most common ice cream flavors–despite the fact that the spice itself was still fairly uncommon.

I made an ice cream inspired by medieval custards from the pre-vanilla days: sage and rosewater.   I used a basic ice cream recipe and added one teaspoon of rosewater, and steeped a small handful of fresh sage leaves in heated milk.  I added one teaspoon of crumbled, dried sage leaves as the ice cream was freezing in the ice cream maker.

I wasn’t crazy about this ice cream, but I wouldn’t call it bad.  Many of the people who tasted it enjoyed it.   The flavors are extremely subtle: if you didn’t know what you were eating, it would be nearly impossible to identify the taste.  It’s vaguely like soap, but pleasant, if that’s possible.

Next: Ice cream of the future!

Origin of a Dish: Chocolate Ice Cream

Ice cream made with 18th century chocolate!

There are only a few more official days of summer left, so I’m going to use them to their best advantage by devouring as much ice cream as possible.   But chocolate or vanilla?  A very important question.  According to the International Ice Cream Association, 30% of ice cream eaters prefer vanilla, while a mere 10% prefer chocolate.

But more important important to me is the question: which flavor came first, chocolate or vanilla?

Some of the earliest frozen desserts were scoops of snow or shaved ice topped with flavored sugar syrups;  sometimes, these were made into icy drinks.  In the Middle East they were known as sharbates or serbets–the origin of the words sorbet and sherbet.

Drinking Chocolate making tools: a pot and mixing device. From Lady Anne Fanshawe’s journal, c. 1665.

Because of the precedent of frozen drinks, some of the earliest ice cream flavors were drinks, like coffee and tea. Which is why chocolate ice cream was invented long before vanilla.   The first frozen chocolate recipe was published in Naples, Italy in 1692 in the book The Modern Steward.   “Chocolate” was popular hot drink in 17th century Europe, and was  commonly mixed with spices like cinnamon, chili peppers, anise, almonds or musk (glandular extracts from the musk deer (eww)).  Today’s “Mexican Chocolate”  is actually a descendant of how chocolate was served in the Spanish court, not how it was served by the ancient peoples of Mexico.

The Historic Division of Mars make a historic chocolate based of an authentic 18th century recipe.   It looks like a chocolate crayon, and is blended with anise, red pepper, nutmeg, orange zest, and cinnamon.

I decided to make a version of the original chocolate using a basic ice cream recipe and half a cup of grated historic chocolate.  Before the 19th century, ice cream was made using only cream, but I think that gives it a borderline buttery texture.  I like a 2:1 ratio of cream and whole milk.

As the cream and chocolate froze in my modern ice cream maker, the rotated action of the dasher release the oils of the ground spices, and made my kitchen extremely fragrant.  Homemade ice cream is supposed to freeze once in the ice cream maker, and then it should go into the freezer, to become hard-packed ice cream.

I stole my first taste of historic chocolate ice cream off the dasher as it came out of the ice cream maker:  it tasted just like a Mc Donald’s chocolate milkshake, which was super weird.  Or at least how I remember them tasting–I haven’t had one since middle school, when my mom would always buy me one as a treat after visits to the orthodontist.  I tasted the ice cream after it was fully frozen a few hours later: the chocolate wasn’t the prominent taste.  Instead, all the warm spices the chocolate was blended with where in the forefront.  Anise was the most pronounced, but without leaving a  liquorice aftertaste.

If you’re interesting in trying this recipe out, you can buy historic chocolate here.  It’s also great hot with lots of cream and sugar.

Menus: Fannie Farmer’s Full Course Dinner

One of the most emblematic cookbooks in American history is Fannie Farmer’s Boston Cooking-School Cookbook.  Called “The Mother of Level Measurements,” Farmer is both credited with bringing standardization to American recipes but, as a result, destroying the soul of American cuisine.

Her cookbooks were promoted as practical and economical: a kitchen guidebook for the everyday women.  But it also included simplified recipes for high-end dishes that allowed any housewife to produce them in her own kitchen.

Interestingly, in the back of the book, she includes a menu for a “Full Course Dinner”: twelve courses designed for the most upscale dinner party.   This menu is republished below.  It would be a hellavu party.

First Course

Little Neck Clams or Bluepoints with brown bread sandwiches. Sometimes canapes are used in place of either. For a gentleman’s dinner, canape’s accompanied with Sherry wine are frequently served before guests enter the dining room.

Second Course

Clear soup with bread sticks, small rolls or crisp crackers. Where two soups are served, one may be a cream soup. Cream soups are served with croutons. Radishes, celery or olives are passed after the soup. Salted almonds may be passed between any of the courses.

Third Course

Bouchees or rissoles. The filling to be of light meat.

Fourth Course

Fish baked, boiled or fried. Cole slaw dressed cucumbers or tomatoes accompany this course; with fried fish potatoes are often served.

Fifth Course

Roast saddle of venison or mutton, spring lamb, or fillet of beef potatoes and one other vegetable.

Sixth Course

Entree made of light meat or fish.

Seventh Course

A vegetable. Mushrooms, cauliflower, asparagus or artichokes are served.

Eighth Course

Punch or cheese course. Punch when served always precedes the game course.

Ninth Course

Game with vegetable salad, usually lettuce or celery; or cheese sticks may be served with the salad and game omitted.

Tenth Course

Dessert, usually cold.

Eleventh Course

Frozen dessert and fancy cakes. Bonbons are passed after this course.

Twelfth Course

Cracker, cheese and cafe noir. Cafe noir is frequently served in the drawing and smoking rooms after the dinner.  After serving cafe noir in drawing room, pass pony of brandy for men, sweet liquenr (Chartrense, Benedictine ,or Parfait d Amour) for women, then Creme de Menthe for all.

The Masters of Social Gastronomy Podcast: RAW MILK!
