Teas or Tisanes?

Real tea plant not some herbal shitI suppose it’s crotchety of me, but whenever I hear the term “herbal tea” used to refer to an infusion of leaves or fruits that contains no actual tea, I get shirty.

They’re actually not tea at all, they’re tisanes, a pleasant French word that means’herbal infusion.’ They should be called such and labelled appropriately in stores.

Tea is, properly a plant originally from China: Camellia sinensis. How the word came to be used as a descriptor for any hot drink in which leaves were infused or decocted, I don’t know, but it’s lazy language; misleading and dishonest.*

Tea drink is, of course, an infusion, but not all infusions are tea. If it doesn’t contain actual tea leaves, it should not be called a tea. Period.

The original word tea itself (te and its Cantonese equivalent, cha) have specifically meant Camelia sinensis in China since at least the eighth century CE. That’s what they meant when European traders started bringing the stuff back. The Online Etymological Dictionary explains some of its European use from the 16th century:

The distribution of the different forms of the word in Europe reflects the spread of use of the beverage. The modern English form, along with French thé, Spanish te, German Tee, etc., derive via Dutch thee from the Amoy form, reflecting the role of the Dutch as the chief importers of the leaves (through the Dutch East India Company, from 1610). Meanwhile, Russian chai, Persian cha, Greek tsai, Arabic shay, and Turkish çay all came overland from the Mandarin form.
First known in Paris 1635, the practice of drinking tea was first introduced to England 1644. Meaning “afternoon meal at which tea is served” is from 1738. Slang meaning “marijuana” (which sometimes was brewed in hot water) is attested from 1935, felt as obsolete by late 1960s. Tea ball is from 1895.

“Herbal tea” might be derived from the Latin: herba thea means “tea herb”(LAtin was still more-or-less a living language in the 16th century) or maybe it, too, came via the Dutch traders: herba thee (which also means tea herb). Either way, we ended up with “herbal tea.”

Whatever its origin, it is incorrect. It’s like pointing to a dandelion and calling it a rose garden because they’re both plants. Or handing someone a cola and calling it a cold coffee because they both have caffeine. The only thing tea and tisanes have in common is the hot water.

Why aren’t these non-tea infusions called “herbal coffees” of “herbal colas”? That would make as much sense as calling them herbal teas.

The Geometry and Topology of Pasta

Pasta by DesignI’ve always had a geeky appreciation – and awe – of mathematics. I have spent countless hours tinkering with programs that create math-based designs like fractals and Spirograph-style curves. As a young teenager I spent hours playing with an oscilloscope making sound waves dance on the tiny screen. But I never really thought much about the math behind pasta until I stumbled on two books: The Geometry of Pasta and Pasta by Design. And once you open them, you have one of those ‘ah ha!’ moments where you discover mathematics and cooking intersect.

These books offer radically different approaches to pasta from my usual reading (and neither are about making your own pasta, although the shapes and histories may help inspire you). What is odd is that both take an unusual approach and yet both were published within a year of one another.

Shape of course matters. The shape of pasta defines several key elements: amount of surface area and size (which matters to cooking and when determining which utensils to use to eat it), thickness (matters to cooking time), sauce holding ability (rough or convoluted shapes hold more when eating) and visual appeal. Shape determines how much water a piece of pasta absorbs, how the heat is absorbed and transferred – knowing these data, one could choose the type of pasta to best match a particular sauce, or vice versa.

Texture, too matters, to sauce retention, cooking and mouth feel, but that’s micro-topology, and not covered here.

The first, The Geometry of Pasta, is really a cookbook designed to both entertain and express the complex design inherent in pasta shapes, as well as offering a bit of history and regional information. It comes from the chef of a very chic UK restaurant ( Bocca di Lupo) and a brilliant graphic designer. It also sports a delightful website in which you can explore the shapes of 77 types of pasta in elegant black-and-white illustrations:

Lasanga ricce
penne

The text that accompanies that illustration of lasagna ricce at the top – the shape for which I recently acquired an attachment cutter for my Atlas pasta machine – says:

Lasagne ricce are crimped, wavy or ruffled lasagne – lasagne with wavy edges – that are decorative and may allow lighter sauces to infiltrate the dish better. This shape of pasta is primarily a southern thing. Across Sicily, baked al forno with layers of a rich ragù and ricotta, it is a staple of the Christmas table.

Under the heading of sauces, there is a recipe for using lasagna ricce which, since it contains mammal meat, I will have to eschew. However, there are other equally attractive recipes on the site (and in the book) I can substitute. If, that is, the authors don’t know I’ve done so. They have written in the introduction, that…

…the Italian “preoccupation with choosing the right pasta shape to go with the right sauce” is not just some silly European thang, but can actually “[make] the difference between pasta dishes that are merely ordinary and truly sublime”.

Reviewer Joanne at Eats Well With Others has written:

Using the geometry of a given pasta – each with its own nuances, personality traits, online dating profile – one can actually turn the art of pasta preparation into a science; an architectural study, if you will.

More Pasta Making

RavioliMy first attempt at ravioli was, I admit, a disaster. But you learn from trying what you need to do the next time. And you also learn from reading what tools you might need to do better. Sure, you can make ravioli and other stuffed pasta by hand, but what I wanted was a plaque. That’s the one I bought in the photo on the right. Simple, inexpensive and easy to use.

A plaque is a die for making ravioli. It has a metal base, 12 holes, with ridged borders around each, and holes. It also comes with a plastic press. A plaque is great for making symmetrical ravioli.

RavioliThe process is relatively straightforward: make your pasta and roll it into a sheet wide enough to lay over the lightly-floured plaque with some on either side. I rolled it out to setting seven (7), which was thin enough so it would cook quickly, but thick enough to be bent into shape when the press is applied. You don’t want the bottom layer of dough too thin or it will tear, but I could have rolled the top layer at 8. Next time I’ll try it.

Gently push the press onto the dough so it creates the indentations, then remove it. Fill with your choice of ingredients (I used Ricotta cheese and finely-chopped sundried tomato). Use a spoon to smooth it into the indentations as necessary. Lay another sheet of dough on top, then use a rolling pin to press the top sheet flat. The ridges on the plaque poke through the dough. Turn it over and tap out the individual ravioli. If you’ve rolled it properly, each piece will separate cleanly.

Resting, Relaxing and Rising

BreadI’ve been reading of late about gluten. How it works, how it develops, why it matters. Gluten is the key to good bread and pasta (the gluten-free fadists notwithstanding, gluten-free anything is an aberration that should be shunned by anyone not diagnosed with celiac disease*).

I’m learning more about how gluten links with itself to form the chains necessary to make our food, and how to improve it in my cooking. The Canadian Grains Commission tells us:

Gluten is a protein composite that accounts for 75 to 85% of the total protein content in bread wheat. Gluten component proteins are found in the endosperm of mature wheat grain, where they form a continuous framework around the starch granules… Gluten forms when water is added to flour and is mixed. During mixing, a continuous network of protein forms, giving the dough its strength and elasticity. By holding gas produced during fermentation, the protein network allows bread to rise.

Key words: “Gluten forms when water is added to flour and is mixed.”

At one point, I tried adding extra vital wheat gluten to my doughs to help create a better crumb when I felt it was failing, but I’ve learned that is unnecessary with the typical unbleached white flour I use. With the mixes of whole grain, rye and heritage flours, however, it might help. But it seems the best remedy is mixing and time.

Recent books on baking bread and making pasta have provided me some new insights into gluten in both bread and pasta, which are, of course, related by their common component: flour. Gluten – the wheat protein strand that gives dough both its plasticity and elasticity – is essential to both bread and pasta. But it doesn’t automatically develop to its fullest without human intervention.

The Big Bake Theory adds:

…there are ways of controlling gluten to obtain the optimal amount of gluten development for the particular baked good you are working with. These include:

  • Extent of mixing
  • Type of flour
  • Amount of water
  • Presence of fats
  • Other such as pH, salt, temperature…

Humans have been eating wheat and its gluten for at least 10,000 years. Approximately 1% of us has celiac disease, a severe intolerance to gluten. Another 3-6% have a lesser intolerance. The other 93% of us can digest wheat and gluten with no ill effect, as we have done so for ten millennia.

Update: expanding my pasta making

Regina pasta makerI’ve just ordered a pasta extruder – the Marcato “Regina” pasta machine, which I expect to arrive in another week. This will allow me to make hollow pasta types like penne and rigatoni, not just the flat varieties I’ve been making to date. The machine got fairly good reviews online at various cooking sites.

These extruders work much like a meat or dough grinder: a corkscrew gear forces the dough through a cutting die that determines the extruded shape and diameter. In fact, they can also be used for making other dough products like biscuits. This one is made from plastic.

On top of that, I received my ravioli plaque last week and will try a batch of ravioli this week using it. This requires making the wide sheets of dough first, as well as a suitable stuffing (I have some cheeses already selected, as well as some fresh kale which I plan to cook then blend into a paste I can include with the cheese, although my first inclination was to use sundried tomatoes).

I’ll have to do a bit of reading on making ravioli first, especially on how to prepare the stuffing so it doesn’t remain too moist. And advice or recipes would be appreciated.

And I also ordered a new cutting attachment for the roller to allow me to make wider noodles: 12mm, double what I can make at present. I’ve been looking at even wider cutters for lasagnaette and lasagne, but they can wait until later.

I’ll post photos and a story about my results, later.
