Celebrating Celeriac with a Superb Soup [Vegan]

Celeriac, before and after a trim.

If there is an uglier vegetable on the planet Earth than celeriac (Apium graveolens variety rapaceum), I have yet to find it. Fortunately, much as beauty is only skin deep, in the case of this magnificent and underappreciated vegetable, so is ugly.

While celeriac itself doesn’t grow very deep — maybe six inches or so beneath the surface of your average garden plot — its roots in food history are deep indeed. In Book V of Homer’s Odyssey, it’s described as a component of Calypso’s garden, albeit in the Greek it is referred to as selinon. In one passage, Hermes admires the environs of Calypso’s cave, festooned with grapes, violets, and wild celery before stepping inside to beseech her to let Odysseus go and finish his journey back to Ithaca. But that’s another, much longer, story.

In ancient times, and for much of their early history, both celery and celeriac were regarded more as medicines than as foodstuffs. Pliny the Elder claimed that the so-called helioselinon was “possessed of peculiar virtues against the bites of spiders.” He also suggested that it could be used to revive sick fish. But by the 17th century, it was being cultivated in France, and by the 18th, it was being used in England for soups and broths.

Fast forward to today: soups and broths! For your consideration, here’s a soup that contains not just one, but two of the planet’s least photogenic vegetables (the latter being parsnips), along with a little ginger (no beauty contest winner itself), some onion, tarragon, and lemon thyme.

CELERIAC AND PARSNIP VELOUTÉ WITH GINGER AND LEMON THYME

Ingredients
48 oz./1.42 litres vegetable broth
2 large celeriac roots, peeled and roughly cubed
3 large parsnips, peeled and chopped
1 large onion, roughly chopped
1 tablespoon (or more, to taste) fresh ginger root, finely chopped
2 tsp./1.2g dried tarragon (it’s what I had at the time; fresh is good too, but use less)
4 sprigs fresh lemon thyme
1 carrot, cut into “coins” (optional)

Before you get all huffy, this is not technically a velouté, inasmuch as it is not thickened with a roux and cream, but it resembles one in texture. If you just want to call it soup, you have my blessing.

Cleaning the celeriac is best done with a very sharp knife, and it may be treated the same way you would strip off the rough outer skin of a pineapple; ideally, you’ll get off all the brown bits underneath the skin, but don’t make yourself crazy (or whittle the vegetable down to half its original size) getting there. Chopping the peeled celeriac is a bit of a chore, and may require rocking your knife back and forth a bit to get through the dense root. Alternatively, you can use a cleaver, if you have one. The parsnips should be scraped with a vegetable peeler, much like carrots, then chopped. As for the ginger, I started with a segment that was about the size of my thumb and scraped off the peel with a spoon before mincing it as finely as my admittedly mediocre knife skills would permit.

Once the prep is completed, making the soup is a snap; basically, you just dump all the ingredients into a big pot, bring it to a boil, and back it off to a simmer for about an hour to soften up the veggies and give the flavours a chance to blend. Then remove the thyme sprigs (which will have shed their leaves), and transfer the soup, in batches, to a food processor, blender, or Vita-Mix. [IMPORTANT NOTE: Do NOT clamp down the lid on your food processor/blender in such a way that steam cannot easily escape, or you will run the risk of both scalding yourself and decorating your walls with hot soup. I leave the top plug out of my Vita-Mix’s “Action Dome” and drape a tea towel over the opening to allow steam, but not solids, to egress.] Alternatively, the soup can be processed in situ with an immersion blender. Process until smooth.

Perhaps not the root of all soups, but it is a soup of all -- well, almost all -- roots.

Perhaps not the root of all soups, but it is a soup of all — well, almost all — roots.

You might note that salt is not a component of the ingredients list, and that’s because the vegetable broth I used (I’m ashamed to admit that I didn’t have any vegetable stock of my own lying around) contained 570mg of sodium, presumably in the form of sodium chloride, which was plenty salty for my taste. Your taste (and your broth) may vary.

To finish the soup off, I sliced a small carrot on a hand-held mandoline, arranged the carrot “coins” into a small “flower,” and sprinkled a few leftover thyme leaves on top. I might drizzle a few drops of olive oil on it as well next time, but it’s by no means necessary. Serves 6-8 (easily!) as an opening course.

All Hail the Green Goddess! (plus a godlike potato salad recipe)

How in the world did we ever get from this…

to this?

Savory & Vibrant. It even says so.

Savory & Vibrant. It even says so.

Funny story, that. It involves a Scots drama critic’s first play, a British star of stage and screen, and a classically-trained hotel chef. [If you just want to skip ahead to the recipe for Green Goddess Potato Salad, not to worry. Just jump down a page or three.]

In 1920, drama critic William Archer took his own advice (from his 1912 non-fiction book Play-Making: A Manual of Craftsmanship) and wrote his first play, something of a pot-boiler called The Green Goddess. It opened, to some acclaim, on 27 Deceember 1920, at the Walnut Street Theatre in Philadelphia, and starred a gentleman named George Arliss. So popular was it that it opened on Broadway (at the Booth Theatre) less than a month later, and toured America for the better part of three years before opening a highly successful (and lengthy) engagement in London.

Along the way — and by the best triangulation available to me, sometime around March of 1923 — it played in San Francisco. While in The City, Arliss stayed at the Palace Hotel (which is still around, incidentally), and dined at the hotel’s restaurant, which at the time was overseen by Executive Chef Philip Roemer. Depending on which story you want to believe, either the chef decided on his own to honour Arliss with a salad dressing inspired by the play, or Arliss himself put the chef up to it as a publicity stunt. Personally, I would like to think the former.

And, before you could say, “Wow, I wonder if this salad topping will still be around and popular nearly a century later,” Roemer had created the Green Goddess dressing. [Before we get into the actual recipe stuff, a couple of notes. Not only was the play successful, but it was made into a movie twice (both times starring Arliss), once as a silent in 1923, and once as a “talkie” in 1930. It’s worth noting that the goddess was more grey than green, as both films were shot in black and white. Arliss was nominated for the Best Actor Academy Award for the 1930 version (he had won the previous year for Disraeli), but ultimately lost to Lionel Barrymore, who won his only Oscar for A Free Soul. In fact, Arliss himself presented the Oscar to Barrymore.]

Much like the salad dressing’s creation myth (even the hotel’s own website has gotten it wrong, predating the play’s creation by half a decade), the “official” recipes for Green Goddess dressing vary widely. And while I mean no disrespect to any of the bottled versions’ manufacturers, do have a go at making it yourself. It’s dead simple, and it tastes so much better. As for the potato salad, which calls in the original recipe for green beans, I think asparagus (if available fresh) is better suited to it. Both provide a bit of toothiness, but roasted asparagus and roasted potatoes mesh like Ginger Rogers and Fred Astaire.

Preheat oven to 400°F/200°C Wash and trim and place in plastic bag with olive oil (you can use the bag from the potatoes if you wish, although you may need to add a little olive oil); shake until coated and arrange in a single layer on a cookie sheet. Liberally sprinkle salt and pepper over. Roast for about 15-20 minutes, or until slightly browned, but still with a little snap. Remove when done, allow to cool, chop into 1 inch/2.5 cm pieces, and place in large mixing bowl with potatoes. Mix with Green Goddess dressing and chill for 1-2 hours in refrigerator. Devour unreservedly.

GREEN GODDESS DRESSING (adapted from Gourmet magazine)
Ingredients:
3/4 cup/180 ml mayonnaise
3/4 cup/180 ml sour cream
3 tablespoons/45 ml tarragon vinegar or white-wine vinegar
3 scallions, chopped
3-4 flat anchovy fillets, chopped, or 2 teaspoons anchovy paste
1/4 cup/10 g chopped fresh flat-leaf parsley
2 teaspoons/2 g chopped fresh tarragon
1 teaspoon/5-6 g sea salt or kosher salt
1/2 teaspoon/2.5-3 g black pepper

Pulse mayonnaise, sour cream, vinegar, scallions, anchovies, parsley, tarragon, salt, and pepper in a food processor until dressing is pale green and herbs are finely chopped. Refrigerate until use. Editor’s note: You don’t have to be either green or a goddess to make this salad spectacular. Although either would certainly enhance the presentation.

Note on metric conversions:
Since American measurements are generally based on volume rather than weight, I’ve had to be a little loose with the metric conversions. For liquids, of course, they are pretty precise, but for dry ingredients, they’re a little more fungible (after all, a tablespoon of salt weighs a lot more than a tablespoon of dried parsley flakes). That said, the Interwebs have some conversion guides that have allowed me to get close, and fortunately, this recipe is pretty forgiving. I suppose in future that I would be wise to use my fabulous OXO Good Grips Stainless Steel Food Scale with Pull-Out Display to give an accurate measurement. But wisdom was never my long suit.
