A couple days ago I foraged Lamb's Quarters and rinsed them, then put them in the fridge overnight. The next morning, I chopped up about 1.5 cups and put them in my frying pan with some blue/red potatoes and garlic. I fried them up and had them for a great mid-day snack.
Then... I started getting stomach cramps about 20 minutes later... which did not go away for several hours. I actually had to go lay down for a bit, which is unusual for me to do.
Afterwards I looked it up - and some people are sensitive to Lamb's Quarters, suffering gastro-intestinal issues from eating them. I guess I might be one of those sensitive people!
So I learned a little lesson about trying new things - eat a few bites and see how things go before eating a full serving of something I'm completely unfamiliar with.
Other than that, my foraging project this month has gone super well. I've made clover jam (a couple different flavors), honeysuckle syrup, honeysuckle tea, elderberry cordial, a plantain infusion that is steeping for salve, and a jewelweed infusion that is also getting ready to be made into salve. :)
