Every generation thinks its own food is normal and everyone else’s is strange. If you go back far enough, though, the menu starts to look less like a cookbook and more like a dare. From fish-gut ketchup to stitched together animals, our ancestors were a lot more adventurous than most of us are today.

In Short

• Our ancestors routinely ate foods that most of us would consider shocking today, often for practical reasons like preservation, religion, or using every part of an animal.
• Dishes like meat aspic, Roman fish sauce, roasted dormice, and blood sausages were not fringe novelties but everyday fare in many times and places.
• Other foods, such as beaver tails at Lent or desserts flavored with whale byproducts, show how religious rules and luxury trends shaped what ended up on the table.
• Some of these foods still exist today, but most of us now experience them as curiosities that tell us more about history than about our own dinner plans.

1. Meat Jellies And Aspic That Were Not Dessert

When I think of gelatin, I picture dessert. For people in past centuries, “jelly” often meant savory meat locked in translucent wobble. Aspic was made by boiling animal bones and connective tissue to extract natural gelatin, then letting it cool into a firm, clear mold with meat, fish, eggs, or vegetables suspended inside. It was a showpiece at wealthy banquets and a practical way to preserve leftovers when refrigeration did not exist.

To modern eyes, a cold slice of chicken floating in shiny jelly looks like a horror prop, but for our ancestors it was a combination refrigerator, serving platter, and status symbol all at once.

2. The Cockentrice – A Medieval “Frankenchicken”

If you have ever joked about “monster food,” medieval cooks actually beat you to it. One of the strangest dishes on record is the cockentrice, which appeared in late medieval and Tudor banquets. It typically consisted of the upper half of a piglet sewn onto the back half of a large bird such as a capon or turkey, or the other way around, then roasted and basted with egg yolk and saffron so it appeared gilded.

This was food as special effects. The idea was not just to feed guests but to impress them with something they had never seen before. The cockentrice makes more sense if you imagine it as live-action clickbait for a world without cameras or the internet.

3. Garum – Fish-Gut Ketchup Of The Ancient World

The ancient Romans loved a condiment called garum so much that they poured it on almost everything. Garum was a fermented fish sauce made by layering small fish or fish innards with salt and leaving the mixture to liquefy in the sun. The resulting liquid was rich in umami and functioned very much like modern Southeast Asian fish sauces.

By modern standards, the production process sounds like a nightmare. Fish guts plus Mediterranean heat equals a smell you probably remember for the rest of your life. Yet Roman cooks and diners considered it essential, and it was traded widely around the empire. It is a good reminder that “disgusting” is often just “unfamiliar.”

4. Dormice – Tiny Rodents As Luxury Snacks

The Romans did not stop at fish guts. They also turned small rodents into finger food. Dormice, fattened up in special jars called gliraria, were considered a delicacy for the wealthy. Ancient sources describe them being stuffed with minced meat or nuts and roasted before serving at banquets.

Today, the idea of passing around a plate of roasted dormice at a dinner party would probably end the party fairly quickly. In a Roman context, though, it was a way to show off refinement and access to special ingredients, much like rare truffles or caviar.

5. Blood Sausages, Soups, And Drinks

Using animal blood in cooking is not unique to any one culture, but some historical examples are especially striking. In many European traditions, including Viking Age Scandinavia, blood was mixed with grain and fat to make sausages after slaughter, turning what would otherwise be waste into valuable calories.

Blood puddings, blood soups, and even fresh blood drinks show up in records from different parts of Europe. To modern diners raised on supermarket cuts, it sounds intense. For people living close to subsistence, it was a practical way to respect the animal and stretch nutrition as far as possible.

6. Beaver Tails That Counted As “Fish”

Religious rules can shape menus in creative ways. In the 17th century, Catholic authorities in North America were asked if people could eat beaver during Lent, when meat from land animals was restricted. Because beavers are semi-aquatic and spend so much time in the water, church officials ruled that they could be treated as “fish” for fasting purposes.

That meant roasted beaver tail, rich and fatty, was officially Lenten-friendly. From a biological point of view this classification is obviously wrong, but from a cultural point of view it solved a very real problem for people living in beaver country who still wanted to honor their religious obligations.

7. Ambergris – Whale Byproduct In Fancy Desserts

Ambergris is a waxy substance formed in the intestines of sperm whales and later expelled into the ocean, where it can age and harden over time. It has a complex, musky aroma and became incredibly valuable in early modern Europe, especially for perfumery. For a time, it also showed up in luxury recipes, including flavored chocolate drinks, custards, and even ice cream.

If you have ever complained about “artificial flavor,” imagine finding out that your dessert was scented with a rare chunk of whale intestinal material. To wealthy diners around 1700, that unusual origin was part of the appeal. It signaled expense and exclusivity in a way few ingredients could match.

8. Insects As Decorated Treats

Eating insects is common in many parts of the world today, but in European history it often shows up in surprising places. Historical accounts from the Renaissance and early modern periods describe people in regions of Switzerland and Germany eating locusts, grasshoppers, beetles, and ants, sometimes prepared with care instead of as emergency food.

Some sources even mention sugared or candied insects presented as novelties for those wealthy enough to experiment. For modern Western diners who may still struggle with a single cricket, the idea of sugarcoated beetles on a serving tray feels like a prank. For people at the time, it was one more way to explore the edible world.

9. Haggis And Other Stomachs Stuffed With Organs

Haggis is so closely associated with Scotland now that it is easy to forget it belongs to a much older family of dishes. The classic version mixes a sheep’s heart, liver, and lungs with oats, onion, fat, and spices, then traditionally cooks the mixture inside the animal’s stomach. Similar “stuff the offal in the stomach and boil it” approaches probably existed wherever people hunted or herded animals and needed to cook perishable organs quickly.

To a lot of modern diners, the idea of eating lungs out of a stomach bag sounds like a dare. For earlier societies, this was efficient, filling, and a way to avoid wasting anything. Even today, people who grow up with haggis often treat it as comfort food rather than shock food.

What Counts As “Weird” Changes Over Time

Looking at these dishes together, I am reminded that “weird” is a moving target. Garum is not so different from modern fish sauce. Blood sausages are still popular in some regions. Insects are being reintroduced as a sustainable protein source. Even the cockentrice, absurd as it seems, belongs to the same tradition as elaborate tasting menus that exist mainly to surprise guests.

If someone from the past could see neon snack cakes, artificially colored sodas, or cheese powder in a packet, they might think our diet is just as bizarre as we think theirs was. In a way, every generation is eating weird food. We just happen to be used to our own.
