I harvest fiddleheads.
I eat them and I sell them at market.
Most of my land is forest some of which has ferns. Fuzzy ferns which are bitter and not good for eating.
Down nearer the river, you descend an embankment, into the flood plain, and on that flood plain is the fiddlehead ferns. When they first pop up, they are bright green and only the brown husk is fuzzy. The ferns have no fur at the time. The heads are curled very tight, and are very easy to pinch off when they are one inch tall, up to maybe ten inches tall.
Most of that swamp stinks from the beaver poo and otter water that it is soaking in. But as the water recedes from each bank, then the fiddle heads will pop up.
Fiddleheads need to be blanched in boiling salt water for 30 seconds, before you freeze them for long term storage.
Whenever you go to eat them, boil them for ten minutes. Do not steam them, they were growing in beaver poo and otter water, likely with salmonella or whatever grows in aqua-mammal slime and feces. Boil them for ten minutes.
Drain the water, and fiddleheads are great!
Fiddleheads can be sauteed in butter
Sauteed in pork lard
Soaked in vinegar
Mixed in with an omelette
