The mafic within refers to the presence of mafic minerals, which are rich in iron and magnesium, within a rock or geological formation. Mafic minerals are commonly found in igneous rocks and are characterized by their dark color and high density. Examples of mafic minerals include olivine, pyroxene, and biotite. Mafic minerals are formed from molten rock, or magma, that cools and solidifies. As the magma cools, mafic minerals crystallize and form within the rock. The presence of these minerals can give the rock a distinctive appearance, often appearing dark in color.
Instead, it's an unusual flavoring component that gives Eau De Musc its signature scent and taste. It’s called castoreum, a secretion harvested from the castor glands of beavers. And whether you realize it or not, you’ve likely consumed it in all manner of foods. House of Tamworth, the distillery that makes the beavery bourbon (currently available for curbside pickup), says that the castor sac excretions impart "bright and fruit qualities (raspberry) and rich leathery notes along with creamy vanilla aroma" upon their hooch. Which frankly sounds delicious.
It was a looooong day, especially for the kids 3-hour bus rides each way, tours of the Capitol building and Sutter s Fort and a jaunt through the Train Museum. I ve eaten things that still give me sense memory nightmares the Brussels sprouts creme brûlée I barely choked down at LL s 50th birthday dinner shows up in my blog posts here more often than I realize.
The presence of these minerals can give the rock a distinctive appearance, often appearing dark in color. One common type of rock that contains mafic minerals is basalt. Basalt is an extrusive igneous rock that is commonly found in volcanic regions.
Who figured out a beaver’s behind tastes like raspberry?
(edited 9/25/2023) By now you may have heard, thanks to Jamie Oliver and Dr. Oz, that castoreum is a natural flavor behind some of the products we consume. I use the word “behind” literally, since castoreum is the product of a beaver’s anal glands. Castoreum is totally unique, chemically speaking, to the beaver – not to be confused with that stinky defensive spray that comes from a skunk’s anal glands, or reason dogs walk in circles sniffing each other’s rear ends. Same place, different thing.
I used to have a photo of dried castoreum here, but decided you can just look it up yourself.
After a considerable amount of research, I’m declaring this NOT urban myth. The 2005 edition of industry handbook Fenaroli’s Flavor Ingredients reports the average part per million range of castoreum extract present in the following consumables: “Alcoholic beverages, Chewing gum, Frozen dairy, Gelatins and puddings, Gravies, Meat products, Nonalcoholic beverages, Soft Candy.” It’s not the only reputable source; the 1980 CRC Handbook of Food Additives states that castoreum adds “unusual notes to raspberry and strawberry.” I also found mention of castoreum in the 2000 edition of the Council of Europe’s Natural Sources of Flavorings, John Wright’s 2004 book Flavor Creation, and the 2011 volume of Leung’s Encyclopedia of Common Natural Ingredients: Used in Food, Drugs, and Cosmetics (this is the one I might be putting on my birthday wish list).
Less certain than the fact that castoreum is added to some of our consumable are the actual products you may be purchasing that contain castoreum. The blogosphere says it shows up in the ingredient list of raspberry-tasting items masked as “natural flavors.” I found this 2009 patent application for a product designed to improve the taste of the potassium salt that can be present in low-sodium items; castoreum is one of the hundred or more ingredients that may help it taste better. The problem is that the term “natural flavors” is a specific designation, defined by the FDA as:
the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional.
Commercial recipes are intellectual property and protected by law. For good reason, just think how many people have tried to figure out the secret behind Pepsi vs. Coca-Cola. And no company, unless they are willing to face a public relations nightmare, will admit to putting castoreum in the ingredient mix for whatever delicious thing they concoct.
To be honest, I’m not too concerned with how disgusting or not castoreum might be. Bring it on, if the FDA approves it. I’ve eaten things that still give me sense memory nightmares – the Brussels sprouts creme brûlée I barely choked down at LL’s 50th birthday dinner shows up in my blog posts here more often than I realize. But much, much, worse that was the limpet sashimi we ate under the stars at the Molokai Ranch after an otherwise lovely and restful day. I’m not here to judge the relative ickiness of one animal product over another: is ingesting castoreum any different from eating any other product from an animal? We eat round steaks, otherwise known as rump roast. Same place, different thing, right?
So the point I find totally unacceptable isn’t in the actual use of castoreum. That’s a different debate. What’s objectionable is the complete lack of transparency behind the FDA’s “natural flavors” designation. A person who chooses to be vegan or vegetarian, or a person with celiac disease or food sensitivities, or a person who just really wants to know what goes in their bodies, can’t consume a manufactured product with “natural flavors” listed as an ingredient, because that bag of “flavors” is just too big. Food manufacturer’s intellectual property is protected, sure, but we consumers lose out on any way to know exactly what we are consuming.
Even the most well-intentioned person could make an erroneous assumption. Here’s an example. I remember watching another mom at a candy store during the 4th grade field trip to Sacramento. It was a looooong day, especially for the kids: 3-hour bus rides each way, tours of the Capitol building and Sutter’s Fort and a jaunt through the Train Museum. Small wonder, by the time we were let loose to go explore Old Town, the kids made a beeline to the candy store.
This is a mom who talked about keeping junk food away from her kids, sending fresh mangos in her daughter’s lunch box, all the healthy things. And there she was in the Candy Store, willing to let her child choose a jelly bean treat. She was carefully comparing ingredients to see which flavors were acceptable. In what I thought it was a funny place to draw the line, those candies that listed “natural flavors” were fine for her daughter to choose from. Any with “artificial flavors” were banned. She made an assumption, like most of us probably do, that if a product has “natural flavor” listed on a package it has some relationship to the flavor of the product – and that’s NOT the case. That “natural flavor” can be anything from aloe to anise to castoreum to civet. Even in berry-flavored jelly beans.
I’ve got to be honest – I can’t help but wonder what genius figured out a beaver’s behind tastes like raspberry. I blame it on the ancient Roman Empire, where by 77 AD or so, when Pliny wrote his Natural History, castoreum already had a long and illustrious history as a homeopathic medication. He lists 66 uses for the extrude, everything from curing headache, neck ache, flatulence, constipation, asthma, and epilepsy, to castoreum being a good depilatory. It was used in medicine well into the 18th century, when castor oil – so named to take advantage of castoreum’s popularity – took over in popularity. Small wonder that sometime over the last 2000 years or more someone started adding it to food.
Castoreum was, and still is, used in perfume making and is present in some homeopathic products. In these cases, castoreum is clearly labeled as an ingredient. That’s much more honesty than in the food manufacturing industry. Food manufacturing – that sounds like an oxymoron, but the truth is that processed food is manufactured to an astonishing degree. Consumers, beware.
Here is an excellent blog post I found by Vancouver writer TJ Dawe about castoreum and flavorings that’s worth a quick read. And on the off chance you’d like to experiment with castoreum yourself and lack easy access to a beaver trapper, just do an Etsy search for dried Siberian castoreum. One Philadelphia distiller figured out how to make excellent whiskey from the beaver butt delicacy. Go ahead – let me know what you come up with.

It is composed mainly of mafic minerals such as pyroxene and olivine, along with plagioclase feldspar. The presence of mafic minerals within a rock can have significant implications for its overall composition and physical properties. Mafic minerals are typically denser and have higher melting points than other minerals, which can contribute to the overall strength and durability of the rock. In addition, the presence of mafic minerals can also influence the rock's color and texture. As mafic minerals tend to be dark in color, rocks containing these minerals often have a darker appearance. The texture of the rock can also be affected, with mafic minerals contributing to a more fine-grained or crystalline texture. The mafic within can also have important implications for the formation and evolution of geological formations. The presence of mafic minerals within a rock can provide valuable information about the source and composition of the magma from which it formed. By studying the distribution and characteristics of mafic minerals within rocks, geologists can gain insight into the processes that shaped the Earth's crust and the history of geological events. Overall, the mafic within is a term that describes the presence of mafic minerals within a rock or geological formation. These minerals, which are rich in iron and magnesium, can have significant implications for the composition, physical properties, and formation of rocks. Studying the mafic within can provide valuable insights into the Earth's history and the processes that have shaped its crust..
