FAQs
Can I use frozen cauliflower for this salad?
It’s best to use fresh cauliflower because frozen tends to become watery when thawed, which can make the salad soggy.
How long should I marinate the salad?
Marinating for at least 30 minutes is good, but letting it chill for a few hours or overnight improves the flavor even more.
