There are several varieties you’ll encounter at the store or farmers market:
- Slicing: the most common variety in stores that can be bitter, have thicker skin, bigger seeds, and are coated in a food-grade wax to prevent moisture loss. These varieties are grown for shipping durability (for example, thicker skin).
- English: these come wrapped in plastic to prevent moisture loss. They have a tinner skin and smaller seeds. They are usually grown in greenhouses (and often called ‘hothouse cucumbers), and have almost no bitterness. They are more expensive than slicing varieties.
- Pickling cucumbers have a thinner skin to allow for better brining. While rare to find a grocery store, farmers markets have them from time to time if you want to make your own pickles.
- Persian: gaining popularity for their concentrated cucumber flavor with no bitterness and few seeds. They are less watery and more crunchy than other varieties. They are smaller and usually come in a pack of 5 or 6.
- Lemon cucumbers are round and yellow. They have a mild flavor that doesn’t taste like a lemon, despite the name.
When are cucumbers in season?
They start showing up in farmers markets around May and last into late September, or into early November if you live in a mild climate. See what else is in season at the same time: May, June, July, August, September, and in some places: October and November.
How to buy & store
Selection: To find the best cucumbers, look for bright, shiny skin, and firmness.
To store: people are split on whether you should store them in the fridge or on the counter (similar to the tomato debate). That’s because cucumbers are sensitive to temperatures below 50F degrees (a fridge is around 38F), causing soft spots, pitted areas, and further decay. Tests show that leaving them on the counter is better, but those tests are in rooms at about 68F (colder than many homes). If your house is hot, you are better off putting them in the fridge.
Cucumbers will last 2-4 days in the fridge and a few days longer on the counter.
Should I buy organic?
Yes, when possible. The health risk of the pesticides found in (and on) cucumbers is high. Based on the information that Consumer Reports published, that means you would need 1-5 servings in a day to exceed the level of safety set by the EPA (Environmental Protection Agency).
Check out this article, “Should I buy organic?” I look into the known health risks, but also try to be realistic and put the whole thing into perspective.
Not all cucumbers are created equally – some varieties are naturally more bitter (American slicing cukes) while others are almost always bitter-free (Persian and English). Environmental stress also causes bitterness. See “Why cucumbers are bitter & what to do about it.”
Bitterness is concentrated on the stem-end, the skin and layer just below. So you can start by cutting off the end and peeling the skin + 1 extra layer.
Next, use salt and sugar to your advantage. Salt inhibits our ability to taste bitterness. Adding cucumbers to a salty recipe like a gyro works wonders. Bitterness is also masked by sweet things, so using cucumbers in a yogurt-based tzatziki dip (which has sugar) can turn out great. Get more ideas in, “How to reduce cucumber’s bitterness.”
Chemical compounds in cucumbers simulate a cooling effect on your taste buds, according to a book meant for food geeks, Taste Buds & Molecules. The author continues, explaining how this cooling effect enhances acidity, bitterness and saltines, reduces the perception of sweetness, and calms hot spices.
