As I've been sharing in conversation with ThirstyBoots, one of my favorite summer treats is fresh peas or fresh green beans, ("snap" beans), fixed this way:
Shell the peas, (get some help, cuz it's time consuming, but worth it!), or snap the ends off the green beans and slice to 1" to 1 1/2" pieces.
Put in a large saucepan and add enough water to just cover the peas, (or beans), and also a dash or two of salt. Bring to a boil and cook until they start to tenderize, (with the beans, you can test with a fork, but the peas you'll have to taste).
Fresh peas, especially, can take a little time ... I've found about 30 minutes, unless you're lucky enough to get early, young peas, (lighter color), then only about 20 minutes.
When sufficiently tender, (do not
over-cook), drain the water and add a large can, (or two small cans), of evaporated milk, and 3 to 4 Tablespoons of butter.
Put back on the stove over low heat, and re-heat, melting butter and stirring occasionally. Season to taste, (I usually find salt & pepper sufficient, but also like to add a little "Jane's Krazy Mixed-Up Salt").
We used to call this type of preparation "creaming", because we'd use real cream instead of the evaporated milk, but I've found the evaporated milk actually adds more flavor.
These are great on their own, but even better with seafood or barbecue. Simple preparation, but you'll find very few things in this life that are as tasty.
Enjoy!
