Most pickled stuff is nice. I don't really enjoy baby watermelons, they tend to be too chewy. But most of anything is great.
Fermented cucumbers top that easily.
We have a field of bear leek in the garden. But we don't pickle it (now you write it, we just might try it) but either eat it as is, or make pesto.
Make sure it's not lily-of-the-valley. If you know them you'll never make the mistake but apparently some first-timers died eating that thinking they have bear leek.
First bear leek should already grow, while l-o-t-v starts in late April. Then bear leek smells onion obviously. Third, different flowers.
