Yes, you can adjust the sugar according to your taste or dietary needs. Some folks like to use a sugar substitute, while others find that reducing the amount doesn’t drastically change the overall taste. If you’re cutting it out completely, you might want to experiment with the vinegar ratio to ensure the salad isn’t too tart.

this is how my mom prepared it for my dad growing up, and just the recipe I was looking for.
Delicious!
Thank you Thank you!! You got these so right! I’m seventy plus, used to make these like Granny since I was a girl! Sad to say I never wrote the recipe down, who could forget something so simple! We’ll I did and try as I may they never tasted quite right! So I started looking for this recipe and it’s amazing what people add to these!😁 Nothing Granny ever had in her country kitchen!
So again that you! God Bless you and keep you in his loving arms!
hi conni! so happy i could help you relive granny’s recipe! she knew how to keep it simple, right. 😊
Yes I made this! Just the recipe we were looking for. I actually tripled it so it would cover more of the veggies. Hubby likes to add cut up on the vine tomatoes to this. He loved it. It’s a keeper & I have it written down in my favorite recipe book.
My sister-in-laws Mother has made this for my family for years,She is in her 90s now and this is the flrst time this summer is not doing a garden. And so she will not be making my fav cucumber salad, I asked her daughter for the reciepe she told me her mom took all the water out of the cuc by putting salt all over them then rinsing them off before making the cuc salad .could this be true? It seems like a lot of work. Have you ever heard of such a thing?? I know she wont give me the recipe…..
Hey Mary, I’ve never heard of that but I could see doing it if you wanted the salad to last days and days in the fridge. I find that scooping out the insides helps a lot though. Bring her some cucucumbers and ask her to make it and just secretly take notes! I bet it’s similar to this one 🙂
“Salting the cucumbers” is normally done for Tzatziki sauce~ You skin them as you would, quarter them lengthways, and cover them with kosher salt~ You leave them in the fridge, on a rack, over night, and you’ll have a a puddle under them in the morning! RINSE THEM THOROUGHLY!! Soak them if you need to in cold water, and they don’t leach moisture into the greek yogurt~ It turns into a mess, if you don’t! bon appétit!
Can u use fresh tomatoes in this???? How would u do it?
I would add a firm tomato like roma, diced it up, and add it with the cucumbers. Should be just fine 🙂
Tastes just like my grandma use to make! So easy, simple, & cheap!
yes emily, you hit the nail on the head! thanks for trying it! 🙂
Was just double-checking my recollection of how my Mom would throw this together in the summertime. It seems almost too easy and I thought I was missing something, but nope! So good.
Yes it’s hard to believe how easy it is!! And cheap! 🙂
I use seedless or English cucumbers, no need to remove seeds; also peel the thin skin in stripes, so pretty when sliced
Absolutely the best! Will be serving all summer at my Cook outs! Thanks!
This sounds so good. Anxious to try.
