Wow, many questions about the wild leeks.
When digging, never take more than 5% of the patch. This ensures the patch will survive and spread for many decades to come. If the patch is where others harvest as well, take much less than 5% of the patch.
Wild leeks are becoming over harvested and now are hard to find in many areas.
Here is a recipe for pickled leek bulbs. This recipe had the least amount of sugar. I would use maple syrup, not honey.
If maple syrup is not available in your area, use the honey or unrefined sucanat sugar. 2 tablespoons of honey or maple syrup = 4 tablespoons of unrefined sugar.
I would skip the boiling water bath and just store them in the fridge. I bet they will keep much longer than 3 months. Put the jars to the very back of the fridge, where it is the coldest, BUT do not forget them there.
Definitely let them sit for 1 week to meld flavors.
