If you've eaten much Japanese food, you know how important seafood and mushrooms are throughout the cuisine. And when I talk about seafood, I'm not thinking about obvious things like sushi. I'm thinking about dried fish and seaweed. I'm thinking about dashi.

So now you've figured out that, when we're thinking about making ramen, we're dealing with pretty large quantities of animal products that are not typically used in American kitchens. Most people aren't too familiar with going out and buying chicken feet or pork femurs. You might not have a good idea about where to go to get these things. It turns out that Chinese and Asian groceries are key, because these ingredients are Asian cuisine staples, especially in soups.
When we did our first ramen experiment, I went by myself to Oakland Chinatown, where I picked a random market and waded in. Heading straight to the butcher counter, I was confronted with a scene quite divorced from that of the meat aisle at Safeway! Pigs on hooks, whole chickens in bags, and a large self-service box of chicken feet. I'm pretty sure I heard the sounds of livestock coming from the back of the store (could have been a “moo,” more likely an “oink”). But because the employee I tried to hale didn’t speak English, another customer had to translate for me (and inform me that they don't actually provide service at the butcher counter). I ended up helping myself to a chicken in a bag after hand-filling a bag of chicken feet. To Hiroko’s great dismay, that bagged chicken came fully equipped with its head still in place. It fell to me to see it off before the experiment could begin.
The next time out, we headed somewhere more mainstream, 99 Ranch. Here we were able to get pork femurs and back fat right at the butcher counter. 99 Ranch is an interesting experience, by the way. Feels like a big chain supermarket in most respects, but you get periodic reminders--such as the packaged off-the-rack pork uterus (etc.) in the meat section--that you are, in fact, not in the neighborhood Safeway. I like going there. Good prices on ITO EN green tea and dungeness crab, etc. etc.
Among the Wonders of 99 Ranch. ITO En's Oi Ocha green tea products. I've had a long-running addiction to the one on the left. For me, it sits at the pinnacle of non-alcoholic drinks.
For the past six months, we’ve done most of our meat shopping either at 99 Ranch or at Berkeley Bowl, which is a good example of a non-Asian grocery that is helpful. You just need to find a place with a good butcher counter and ask what they have. Sometimes you can’t get pork femur, for example, but you can substitute backbone or neck bone. Fortunately, all these seemingly unusual cuts of meat are readily available from standard meat suppliers, so when you open a restaurant, it’s a lot easier to get what you need on a regular basis than it may be doing ad hoc retail shopping for your own kitchen.
Next up, meatless soups. . . . But first, here's a photo of our Halloween weekend ramen experiment. Would be more effective with a cauldron, but still seasonally appropriate in a Calphalon stockpot:
Double, double toil and trouble. Is making ramen always this spooky?
Ramen 101.2: Soup Basics—Pork and Chicken
Although the most fundamental element of "ramen" is the noodle itself (a special wheat noodle treated with alkaline salts), we tend to think of "ramen" in terms of the soup in which the noodles (usually, but not always) are served. The soup, after all, is the source of so much of the flavor and richness that makes ramen so good. So where does that flavor and richness come from?
Well, it comes from extracting all sorts of compounds like amino acids, polypeptides, and fats from animal bones by boiling them for extended periods. Usually we’re talking about pork and chicken bones. But other flavor sources are also common: dried fish like katsuobushi (bonito flakes) or niboshi (anchovies) are big in Japanese cuisine, as are mushrooms (like shiitake), and kombu (a type of dried seaweed). As you can see in this link and this link (yes, the Umami Information Center does exist), all of these ingredients are big in sources of umami: glutamate and ribonucleotides like guanylate and inosinate. It’s also common to use vegetables like onions, which will endow the soup with added sweetness. In our ramen experiments, we’ve made use of all these things.
The Meats: Pork and Chicken.
Pork is an extremely common ingredient in ramen. In general, we’re talking about pork bones: femur bones, neck bones, back bones. You can make ramen soup with any of these. There doesn't appear to be a strong reason to use one or the other, but some chefs do have a preference. Practically speaking, cost, availability, and process issues are likely to dictate one's choice. For example, femur bones may be more expensive and have a lot of marrow, but you have to break them and cook longer to complete the extraction.
It’s also common to make your chashu topping by boiling pork shoulder (aka pork butt) or pork belly with the bones when making your soup, then removing the meat, marinating it, slicing it, and setting it atop your ramen. And have you ever heard of back fat? This is the layer of fat right under a pig’s back skin. It can be used to add more flavor and thickness to your soup.

Chicken is also very common, and is often used in combination with pork. For some applications, chicken parts are used. I’m talking about chicken backs or frames, chicken necks, and chicken feet. In Japan it’s common to use torigara, which is a cut that includes both the back and the neck. In other applications, a whole chicken can be used.
Soup Categories: Paitan and Chintan
A fundamental point about ramen soups is that they can be loosely divided into two main categories. Paitan (白湯) (meaning “white soup”) is a thick, cloudy soup. Chintan (清湯) (meaning “clear soup”) is clear, exactly as the name implies.
As an example, tonkotsu ramens are almost always paitans. These soups are thick and creamy. They're full of fats and collagens extracted from pork bone marrow and cartilage. The fats provide tons of flavor, while both add body to the soup. If you cool a thick tonkotsu broth, it will rapidly solidify. But you can make chicken paitans, too. These toripaitan ramens have been ascendant in popularity in Japan over the past decade. Although the Japanese tonkotsu boom ended around the time the toripaitan boom began, tonkotsu ramen is still hot in the U.S. Using chicken feet is a key aspect of toripaitan: they are a great source of collagen and soup body.

The main difference between paitans and chintans lies in their preparation. Higher temperature and more robust boiling will make a paitan, while chintans are produced by heating at sub-boiling temperatures. High temperature produces an emulsion, which is a mixture of normally immiscible liquids (like oil and water). Lower temperature cooking allows the fats to separate cleanly from the aqueous soup; the fat can be removed and even used later as a flavored oil topping.

Roughly speaking, pork with its capacity to impart body and richness, is good for making paitans. Chicken, which contains a lot more glutamate (read: more umami) than pork, is good for making chintans. In practice, it's common to combine pork and chicken. And there's a scientific reason for this relating to umami synergy. Look forward to future posts about this fascinating phenomenon.

Ramen 101.1 – Let's Talk About Ramen!
So, yes, we've eaten our fair share of ramen. But, to restate the obvious, eating it doesn't tell you a whole lot about how to make it. As soon as we decided to make a go of it with Shiba Ramen, we dove right into our ramen education. Now, over six months into the project, we've learned a lot. We're still learning a lot, but we're getting into the territory of fine detail. We've got a good handle on the basics. Hiroko's ability to access Japanese-language materials (not to mention the ten days she spent at ramen school last October) has been predictably invaluable.
This is the first in a series of posts about ramen. I'm going to break down the cuisine into its constituent elements. This process should make it abundantly clear that ramen isn't what I called “ramen” in my room in Bradley Hall at Ohio State University in 1996 (or what you called “ramen” in your own dorm room). Lest there be any confusion on this point, I defer to Wikipedia:
Today, just a short intro into the elements. I'll detail these in the rest of Ramen Chemistry's Ramen 101 Series.
Soup stock. This is the core of the product. Making it involves boiling pork or chicken bones (often both together) for an extended period. I'll explain later how different parts of these animals contribute different features to the soup. Believe it or not, chicken feet have a very useful function here. Other umami-imparting ingredients—mushrooms, kombu, dried fish like niboshi or katsuobushi—also have important roles to play, especially if you seek the more complex flavors found in Japanese cuisine.
Tare. Tare (pronounced "tar-eh") translates literally as “sauce.” It's—for example—the miso or shoyu (soy) concoction that takes your soup stock and transforms it into miso ramen or shoyu ramen.
Noodles. Alkaline wheat noodles (no, ramen is not gluten-free). You can make them or buy them from Sun Noodle.
Oils. Flavored fats floating on the soup surface. Res ipsa loquitur.
Toppings. Ramen enthusiasts know that chashu (boiled and marinated pork shoulder or belly) and soft-boiled eggs are traditional ramen staples. But there's a lot that can be done here.
As you can see, we have much to discuss.
It all begins here: a pot full of chicken and pork backbones. Ramen school, October 2014.
A Brief History of Ramen, California Edition
Ten years ago, Hiroko and I moved to California, spending our first six years here living in the Asian food hotspots of Silicon Valley and the Peninsula (we lived in Palo Alto, Mountain View, and Burlingame). There are so many great hole-in-the-wall Japanese places in that area. One of our favorite sushi places, for example, was Kitsho—not a particularly inviting place, sitting as it does next to a strip mall and behind a gas station near Apple’s headquarters in Cupertino. But the sushi there was amazing. When we moved north to Burlingame, we discovered Sushi Sam’s in San Mateo. Like Kitsho, you don’t go to Sam’s for the ambiance. But when you taste his seared toro with sea salt and yuzu at the end of the omakase, you may have a transcendental experience. I did, on multiple occasions.

When we lived on that side of the Bay, we had routine access to ramen. Some of it was really good, some not so much. But we could get it when we wanted it. There were a couple of decent places in Mountain View at the time, but San Mateo was a real mecca. Santa Ramen was always heralded as the gold standard around there, although I found it a bit salty for my taste (fortunately, by that time I’d grown more cautious about guzzling the soup) and a bit too crowded.
Our favorite was Himawari. Not because the ramen there outclassed a lot of the other ramen places in town, but because Himawari made an effort to be a better overall customer experience. It wasn’t dumpy like so many of its competitors’ spaces were. The décor was tasteful and modern, the lighting intimate, and there was always great music (usually jazz). The lines were rarely long, and we could usually sit at a comfortable table and enjoy a quick meal. It was a go-to comfort food restaurant for us. Like I said, that’s because Himawari combined quality ramen with a great holistic customer experience.

Three years ago, we moved to the East Bay. While there is some excellent Japanese food on our new side of the Bay, in Oakland or in Berkeley, the fact is that the Japanese food scene from San Jose through San Francisco simply outclasses the East Bay, in terms of both quantity and quality. When it comes to ramen, there isn’t a whole lot. There are a couple of fancier ramen places, but they are pretty expensive and the lines are long. But we view ramen as comfort food: food that you can eat when you want at relatively low cost. We enjoy ramen the most when the barrier to eating it is low.
As Hiroko tells it, ramen is viewed as fast food in Japan. Not “fast food” in our typical American vernacular, usually referring to lower quality, mass produced food. Rather, fast food in the most basic sense—food that is fast to get, and fast to eat. Calling it fast food in this sense renders no judgment about the quality of the food or the way it’s produced. It simply connotes the investment of time the consumer must make to enjoy the meal. It goes without saying that the meal can still be high-quality and delicious. For us, it just shouldn’t involve making a reservation or waiting in a long line, followed by a hefty bill at the end of the meal.

Does that make sense? Over the next couple of posts, I’ll explain how these observations led to the idea for Shiba Ramen.
