Sounds like a cheesy vampire novel, but all I see are deep colored berries entering the mix: black raspberries, blueberries, and darkest of all, mulberries. Oh yeah, the strawberries are still ripening, too.
Whenever I pick black raspberries, I always remember a story I read as a child, “Green Black Raspberries are Red.” This is true. For any raspberry, you have to wait until the fruit comes off with the slightest tug. The same goes for blueberries: no matter how purple it looks, I test them to see if the stem breaks easily enough to let go. Mulberries are easy. Once they turn that nearly black purple, they drop into your hand at a touch.
Now if I could only remember how to tell if peaches are ripe. They’re next.
