In the Czech Republic, tomatoes ripen in July and August when they are at their sweetest and most flavorful thanks to the sun. That is why this tomato salad is a summer favorite-it is not only delicious but also super refreshing.

Petra,
My grandma Elizabeth from Hungary made this tomato dish all the time during the summer and taught me so I make it, as well. It is so refreshing. Sometimes she would add cucumbers to it. Thank you for bringing a beautiful memory to mind.

Linda, thank you for sharing this. How lovely that your grandma Elizabeth from Hungary made it too, cucumbers and all. These simple summer dishes travel across borders and stay in the family. I am so happy it brought her back to you for a moment.

Reminds me of a salad my mom would make using a bit of balsamic vinegar. Our tomatoes are getting ready to come in so I’ll me making this for a quick, easy meal often!
Petra Kupská says
Ann, a splash of balsamic sounds like a lovely twist, your mom knew what she was doing! There is nothing better than this salad made with tomatoes fresh from your own garden. Enjoy it all summer long.

I have been following your blog ever since our return from visiting your beautiful country. It was our first visit but we hope not the last. I have learned so much about the Czech people and culture from following your blog. Thank you!
The tomato salad was my first recipe to actually try, and it was so good! And so easy to put together. I used ripe tomatoes from our garden. It was the perfect side salad to the pork dish I prepared. And so refreshing during these HOT summer days here in the United States.
Thank you and your family for keeping this blog!
Petra Kupská says
What a lovely note, thank you. It means a great deal that our little country and its food stayed with you after your visit, and that this salad, made with your own garden tomatoes, was your first try. I hope it is the first of many, and that you make it back to us one day.
Geri Repass says
Yes! Oh, so simple and so good! This brings back so many memories! I grew up in the country in Ohio. My parents had a huge vegetable garden on our 2 acres and always juicy tomatoes. I remember having simple salads like this so often. Sometimes my mother would cut up a Klobas and put it in the salad, too. That with a piece of rye bread was heaven on a hot day!
Petra Kupská says
Geri, what a picture you painted: the garden, those juicy tomatoes, a little klobása (Czech sausage) and a slice of rye bread on a hot day. That is exactly the kind of simple food that tastes like home. Thank you for sharing this, it made me smile.
Lili says
I love this salad and make it all year round. The vinegar I use is seasoned vinegar with the acidity only at 4 or 4.5% - much less than the 8% and less than all other vinegars, flavoured or otherwise on our local grocery shelves which usually are 5% acidity. Because this vinegar already contains some sugar, I use less sugar on my salad. I usually add herbs - lately my favourite is tarragon, but any favourite herb will do. Many people prefer basil, but I like the lemony-liquorice-peppery flavour of tarragon. Thank you for posting all these wonderful Czech dishes, Petra. I love them all!
Petra Kupská says
Thank you so much for the reminder about vinegar acidity, Lili! Here in the Czech Republic we tend to have very strong 8% vinegar, so the amount always has to be adjusted to taste. Estragon is a wonderful idea as well. Thank you for sharing it!
