February 24th ……….. National “I Hate Coriander” Day!

February 24, 2024

Honest …. You can’t make up this stuff! You’ve got to wonder what the person or persons who began the National social media movement, “I Hate Coriander” Day, have against an innocent little herb.

“National I Hate Coriander Day, celebrated annually on February 24th, is a social media movement to express disdain for the herb coriander (also known as cilantro) and its taste and smell.”

“Hate” is such a strong word under any circumstances, but to “hate” an herb? … What do these Coriander “Haters” find offensive about the look of this bright green leafy plant? What is it about the taste and/or smell of Cilantro that elicits such a strong reaction? Now I’m not a Coriander (aka Cilantro) addict ….. a bit now and then as garnish or to flavor a fresh salsa is perfectly fine with me. I’ve even grown Coriander in my garden and marveled at the plant’s growth rate, intense leaf and stem coloring, bouquets of delicate flowers and abundance of seed. So my curiosity was definitely piqued when I came across this peculiar National Day. Just what is it that has and keeps these people all riled up over Coriander?

Coriander – The Plant

Not to be confusing, but Coriander and Cilantro are actually the same thing, Coriandrum sativum. However, in the U.S. we tend to refer to the leaves and stems as Cilantro; the seeds (whole raw or toasted, or ground) as Coriander. But because the National Day is about hating Coriander, I’ve made a leap in assuming they hate the entire plant, including the roots, stems, leaves, flowers and seeds (all of which are edible; all of which are eaten). 

The plant is an annual that grows up to 20” tall. The bright green leaves are variable in shape, broadly lobed at the base of the plant, and slender and feathery higher on the stems. Flowers are arranged in umbels (like a wind blown, inside-out umbrella), are white to pale pinkish-mauve. Each asymmetrical flower has longer petals pointing away from the center of the umbel than those pointing inwards. And each flower produces a dry globular fruit (schizocarpic cremocarp) about 1/8 – 3/16” diameter, which splits when mature into 2 mericarps, each mericarp with a single seed.

Coriander – The Seed

The name, Coriander, is the common name used around the world, for the seed of Coriandrum sativum. There are two cultivated varieties of Coriandrum sativum grown around the world.  Although the plants of both varieties appears the same, it’s the seed where the visible differences occur.  C. s. var microcarpum is the small-seeded variety found in temperate climates, such as in Europe and the U.S. Its seeds are about 3 mm in diameter, round, and very potent as a spice. C. s. var macrocarpum (aka C. s. var vulgare) is the large-seeded variety found  in hot, subtropical areas of Asia and India. It’s seeds are 5 mm in diameter, football shaped and have a very delicate flavor.

If you’ve ever grown Coriander from seed, you probably planted one seed at a time, being careful to follow the spacing instructions on the package. Then when your seeds germinated, sending up those first immature leaves (cotyledons), you noticed that for each seed planted there are 2 little plants!  “What the heck?” you say. When you sowed the seeds in each well-spaced spot, you obviously planted an entire globular fruit (both mericarps at once) resulting in the germination of both seeds!

Is There a Consensus of Opinions on Leaf Taste and Aroma? 

Nope! Opinions are far from consensual. As a matter of fact, they are frequently polar opposites. Coriander has been described as the “Marmite”*****!!! of herbs; either you love it or hate it. This great analogy reflects how strongly people do feel about flavors of their food. 

Opinions on leaf taste and aroma: The good – tart, lemon-lime, fragrant, pleasant, distinctive, spicy hot, peppery, aromatic.  The bad – bitter, stinky, unpleasant, nasty, fetid. And the bleh – The leaves smell and taste like dish soap!

Is There a Consensus of Opinions on Seed Taste and Aroma? 

Again, Nope! But curiously, most of the opinions about seed taste and aroma were fairly positive, provided the correct variety of C. sativum was properly prepared and used. For example, all seeds contain 1% volatile essential oils, but the quality of oils is different between the two varieties. For some reason the smaller European variety seeds (C. s. var microcarpum) have far superior essential oils resulting in far superior flavor and yield when compared to the larger India variety seed (C. s. var macrocarpum). The larger India variety seeds are preferred as a spice, both whole and ground.

Opinions on taste and aroma of fresh or dried seeds: Spicy, earthy, cumin-like, orange peel, aromatic, dried seeds have full flavor, fresh seeds are undesirable.

Opinions on taste and aroma of toasted seeds++, whole or ground: Fruity, Fruit Loops, lemony, floral, mild perfumy, aromatic, bitingly pungent, delightful bouquet, distinctive flavor.

Now it’s your turn! Where do you stand on the issue of Coriander; it’s taste and smell? Are you celebrating today’s National “I Hate Coriander” Day? Or are you a regular Coriander Connoisseur, savoring the taste, smell and texture in all of your favorite dishes, from sauces and marinades, curries, meats and seafood, stews, to pastries and desserts? 

***!!! Marmite! Invented, made and sold in England, this stuff is a sticky, dark brown paste made from fermented yeast. It has a very salty and powerful (understatement) flavor, and is frequently slathered on toasted breads like jam. If you haven’t experienced Marmite, perhaps you’ve dared to taste its equally unappetizing knockoff, “Vegemite,” found all over Australia? If you’ve tasted either or both (wow, you’re tough), what was your reaction? If you’ve never had the culinary pleasure, consider this fair warning! Wonder if there’s a social media group that’s declared “International I Hate Marmite (Vegemite) Day?” I would happily eat a bushel basket of cilantro greens, than dare give these yeasty products another go. (No offense to the marmite and/or vegemite lovers of the world.)

++Toasting Coriander Seed: In a non-stick skillet, over medium-high heat, add the seeds. Keeping the skillet in constant circular motion. When the seed’s aroma is released, toasting is complete!  Cool completely and grind with mortar/pestle or in a small electric grinder. Store ground coriander in a cool (refrigerated) location, away from light and moisture. It’s best to toast and grind seeds in small amounts, on an as needed basis, to experience the full flavor.
