Sage goes well with hearty sausages or bratwursts and onions. First, caramelize the onions. Thinly slice two large onions (yes, you'll have a lot, but once they are caramelized you'll end up with far less than you started with). Put a couple of tablespoons of oil or butter into a large skillet over medium heat, add the onions, and sprinkle a little salt over them. (I use a combo of half olive oil and half real butter.) Then let the onions cook for at least 45 minutes, up to an hour. Low and slow is the way to do it. The onions will turn soft, golden and amazingly good. Near the end, say the last 15 minutes, add thinly sliced fresh sage leaves. Spoon the onions and sage over your favorite grilled sausages or brats in a hearty roll for a wonderful sandwich.
If you've got sage leaves you don't know how to use up, make a simple compound butter, which is just a butter to which you've added herbs, or spices, or other flavorings. A sage lemon compound butter is delicious, easy to make, and lasts a long long time in the freezer. Just get a pound of good quality real butter (not a spread). Unsalted is preferred. Let it soften to nearly room temp. In the meantime, finely mince the sage, and zest some lemon peel (being careful not to zest too deeply because the white part is bitter). You'll need the zest of two or three big lemons. Then, in a mixer, cream the butter until it's fluffy and light (just a few minutes). You can also do that part by hand with a sturdy wooden spoon and Wonder Woman arm muscles. Add in the chopped sage and the lemon and mix briefly until combined. The butter should be uniformly flecked with the green sage leaves and the yellow lemon zest. Place the entire bunch of butter on parchment paper and spread until it's the shape of a log, about 2 inches in diameter. Use the parchment paper to roll up the butter (like a chef rolls sushi, using the bamboo to control the roundness of the sushi roll) and make the log even. Twist the ends tightly, label the parchment paper, and place it in a freezer bag. When you need it, slice off a quarter inch or thinner slice of the butter and return the log to the freezer. Place the slice of compound butter on a hot steak when it's ready to serve, or on a piece of grilled chicken, on a pork chop or any pork cut when it's done, on hot cooked pasta, or over baked potatoes, or on pureed winter squash.
If you drink alcohol, you can google sage in cocktails and there are lots of recipes. Or add sage leaves to homemade lemonade, along with a couple of summer berries like strawberries and blueberries and raspberries. Lots of recipes online for sage lemonade, some non-alcoholic, some with vodka.
