Frequently Asked Questions

How long does cucumber onion and vinegar salad last in the fridge?

Stored in an airtight container or glass mason jar, most vinegar-based cucumber salads stay fresh and crisp for 3 to 5 days in the refrigerator.

Why do cucumbers get soggy in vinegar salad?

Cucumbers naturally contain over 95% water. As they sit in salt or vinegar, liquid draws out. To keep them extra crunchy, purge excess water with salt in a colander for 20-30 minutes before adding your marinade.

Which cucumbers are best for vinegar salad?

English cucumbers or Persian cucumbers are best because they have thin skins and very few seeds, meaning less excess moisture and maximum crunch!
