Simply add water to your collected nettle leaves and heat to a near boil. Use about two cups of water for a cup of leaves; there’s no need to measure. You can make the tea stronger by steeping longer, or weaker by adding more water. Once the water is near boiling, reduce heat and simmer for a couple minutes. Pour through a small strainer and the tea is ready to drink. Some people prefer a small bit of sugar added to the tea, but I find the taste is just fine without any additives.
The cooked leaves can also be eaten with a bit of butter melted over top, or they can be added to soups and stews. If you are going to eat the leaves, taste a small bit first to be sure the sting has left.
