Does the peeling method of cucumbers prevent bitter taste?

I find conflicting opinions whether peeling cukes a certain way prevents bitter taste. One recommendation is to start peeling the cuke at the blossom end, and wash the knive after each stroke. Other views say it does not matter. I would like to seed some cukes for late season harvest, but that's when I had bitter cukes in the past. If the way of peeling makes a difference, I'd give it a try.

Learned this back in the 70’s from a coworker, who learned it from her mother. Before peeling, tap each end (rounded) about 6 times on the counter. I swear it works getting rid of bitterness.

I don't do this as I buy my cucumbers at the Farmers Market and they always taste deliciously. However, when I lived in Italy we had a sort of grumpy housekeeper who was a very good cook. When my mother finally came to visit after many years she earned Maria's affection one day when she prepared a cucumber with the rubbing/milking trick. Maria hadn't seen anyone do that since her grandmother in Sardegna more than 50 years ago. From then on they spent the afternoons in the kitchen cooking together, laughing and using sign language.

Interesting, like SKK says, according to Washington State University peeling makes no difference. Oregon State University, on the other hand, quotes a vegetable crops professor at the University of Florida Institute of Food and Agricultural Sciences who came up with the method I described in my initial question of peeling a cucumber to avoid serving bitter-tasting cukes. @ susan g / Panfusine: the "Chinese" rubbing trick is totally new to me and I'll try it just for fun, even though it might be as unscientific as the peeling trick. - So the best way to go about late cukes is to cut off both ends and have a bite before dumping it into the salad or whatever you are making. Sounds obvious but I have spoiled dishes that way. And, have a backup dish because if the cukes are bitter, there is nothing to be done.

Yes Susan G.. I grew up believing this. its second nature by habit to rub the cut surface with the bits cut off from the ends of the cucumber. So glad that some one else bought it up.. (was a bit embarrassed to share this first, silly as it may sound!)

A friend uses this technique to take out the bitterness, purportedly Chinese: cut off about 1/2" from the end. Rub the cut surfaces against each other until it gets a bit soapy/foamy. Anyone else heard of this?

My grandmother was a farmer's daughter and a farmer's wife and she always rubbed the cucumber ends even on the thousands she grew.

Even good garden cucumbers sometimes turn bitter when they are stressed---generally hot conditions and a lack of water. The plant is often near its useful end, too; first cucumbers are never bitter. Sometimes, per SKK, cutting the end off does help, and sometimes, as she says, they're too awful to save. I think the long Asian kind, like Suyo (I grow them on a trellis), are less likely to turn bitter in the heat of August. The peel itself isn't a factor.

Sorry for the spam, everyone! We're still working to resolve this.

I always peel the regular "garden" cucumbers I get at the grocery store. Not for bitterness, but because the skin is waxed to preserve the "freshness". I don't peel cukes I get from the farmers market or from my CSA, nor do I peel the ones that are labeled as "English" or "hothouse" cucumbers. They're easy to spot, they're packaged in a plastic shrink-wrap. I've never found them to be bitter, regardless of peel or seeds.

According to Washington State University, the way you peel makes no difference. Cucurbits is what causes the bitterness and there appears to be more complaints of the bitterness in years with a cooler growing season. Personally, I have found that the most bitter is in the ends of the cucumber so I slice them off. Then I taste a bit unpeeled and if it is bitter I peel. If it is still bitter I scoop out the seeds. If that doesn't work, throw it away.
