While we were visiting a friend in his home (lucky us, he had invited us for one of his fantastic brunches), he asked about the purple string beans:  Do they, he wondered, taste any different from the green ones?

It is a good question.  Purple is an unusual color in the vegetable garden, second only to blue in rarity (is there any blue comestible other than blueberries?).  And while color is not always an indicator of flavor—the taste of red and green apples is not that different, for instance—it can be, especially when the color difference is due to ripeness, or lack thereof.

The answer to our friend’s question, though, is:  No; the purple string beans taste more or less the same as do the green ones.  In fact, as the beans cook, the purple fades away, leaving only the familiar green tint.  This is because heat and loss of acidity (due to dilution in neutral water) break down the anthocyanins that produce the color purple.  Chlorophyll, the green pigment (and component of photosynthesis), is apparently more stable.  (If we grow the purple string beans again next year—which is likely—I might try cooking a batch in vinegar or lemon juice to see whether that preserves the purple color.)

That matter resolved, I’ll ask my own follow-up questions:  What about the other vegetables growing in our garden?  Does their color dictate the flavor?

Well, as an indicator of ripeness, sure.  An unripe green tomato has a vastly different taste compared to a ripe red one.  We don’t grow them here, but apples (and most other fruits) exhibit this property.  It should be noted, however, that not all vegetables change color as they ripen.  Eggplant, for instance, starts purple and stays purple throughout its growth (and even its blossoms are tinged with purple).

But what about different colors of ripe tomato?  Do the yellow and orange varieties have a different flavor from the traditional red ones?  How about tomatoes that are green when ripe?  Furthermore, are the differences in flavor, if any, due to the color or is the color just an indicator of the difference?

Answering the last question first, I think the color is merely an indicator of a difference in flavor and not the cause of it.  The various colors of tomato do have varying flavors but the variations are due to different levels of sugar and acidity.  And as noted above, pigments react very differently to acidity.  Typical red tomatoes are relatively high in acidity so acid-resistant pigments like carotenoids (of which lycopene is the most common in tomatoes) will dominate their color.

At the other end of the spectrum (in both flavor and color), orange, yellow, green and purple (sometimes referred to as black) tomatoes are sweeter in flavor, a result of their being lower in acid.  Another consequence of higher pH is that pigments less resistant to acid, such as the anthocyanins, can survive in their colored state and contribute to the tomatoes their distinctive hues.  In other words, the pigments act as a natural litmus test to visually signify flavor.

This is only a quasi-scientific analysis but it makes sense, at least for the tomatoes.  In addition to the tomatoes, we also planted different colors of carrots, radishes, beets and bell peppers this year.  To my taste buds, the red and white-striped Chioggia beets tasted the same as the Touchstone Gold and neither tasted any different from the typical all-red variety.

Similarly, there was only one significant difference between the taste of our Quadrato d’Asti Rosso (red) and Orange Sun (guess) bell peppers and the common green variety.  The peppers we grew tasted less grassy, a flavor component that I can only call “green”.  This is a good thing because that grassiness usually puts me off bell peppers.

Our radish crop was not sufficiently successful to make an assessment of their flavors but the carrots, which flourished a wide rainbow of colors, also yielded an array of flavors.  The orange were the most typical (no surprise there) while the yellow and white were woodier and the purple were sweeter.  The range in flavor was not quite as great as in color or as stark as with the tomatoes but there was definitely a correlation.

The farmers’ market in my boyhood home has become quite an elaborate affair.  It is located in the town’s Central Park, the southern half of which was a vacant lot when I was in school (my brother tells me the former Central School was located there until just after my family arrived in the early 1960s), under a large steel canopy erected solely for the market.  The structure resembles a long, open barn—such as would be found on a dairy farm, for instance—which I am sure is no coincidence.

The market runs the year ‘round (yet another advantage of the mild valley climate) and attracts many vendors.  The Saturday morning gathering, which we visited during our visit (I’m a bit out of sync here) in anticipation of a later picnic with my brother, was crowded and bustling with more stands than could fit under the canopy.  At least half a dozen stalls extended beyond the north end.  Luckily, the weather was clear and warm (also auspicious for our lunch) and no one seemed to mind being out in the sun.  The market also operates on Wednesday evenings; in the summer, local restaurants set up booths and sell picnic dinners.

Whereas the produce at our market at home is becoming limited to fall staples like squash, potatoes and hardy greens, the fruits and vegetables here are still of the spring and summer variety.  There were strawberries from Watsonville, grapes from Fresno and berries from a variety of towns I didn’t recognize (one complaint about this market is that the vendors are not restricted in the distance between here and their farms).

The grapes in particular caught our eyes both for their freshness and spectrum of vibrant colors.  This bounty also produced similarly multi-colored raisins that were delectably plump and moist.  We purchased a few bunches of grapes for our picnic as well as a bag of raisins to take back home.

Also of note were the nuts and dates.  The nuts arrived from some of the nearest farms—there are large groves of almond and walnut trees immediately to the west of town—and were probably harvested only days ago.  We bought a bag of roasted almonds (with olive oil and salt; yum) for snacking and resisted the urge to buy one of every other variety (our suitcase can only hold so much).

The dates, on the other hand, probably traveled the farthest, having been grown in the Coachella Valley in the southern end of the state (at Leja Farms).  I have no idea when they would have been harvested and only know that they take a while to ripen after picking.  After tasting a few samples, we picked out a large container of large medjool dates.  They were the largest I’d ever seen and had a smooth, velvety texture and intense sweetness.

At most, I think I could eat only one or two at a sitting (yes, that sweet) but they will be a wonderful basis for sweetbreads and milkshakes (a favorite, but maybe that’s another post) and a nice addition to salads (particularly with spinach and fennel).

As we were paying, the farmer asked where we were from and when we responded (New York), she threw in another small container of dates as a reward, I guess, for coming from so far away just to buy her dates.  It turns out that she grew up in an Amish community in northwestern New York and spent a lot of time traveling between there and other Amish enclaves in northeastern Ohio (she was growing apples at the time).  We lived in Oberlin, Ohio for a couple of years and mentioning this fact only strengthened the spontaneous (albeit temporary) bond between us.

We thanked her for her act of (near-random) kindness and vowed to pay it forward by sharing the dates when we returned home.
