I am blessed with two lemon trees and we are in the prime of lemons right now! Despite the harsh winter, the trees and fruit survived. Our oranges are about done, so now we are onto lemons! You can, of course, just squeeze some lemons and add some sugar and water and have decent lemonade. But I find the sugar doesn’t dissolve well in the cold water. If you make a simple sugar syrup instead, it’s much better!
My youngest added half a fresh squeezed orange to her glass and loved the combo. We’ve got just a dozen or so oranges left on the tree.
I also like to mix up everything except the water and keep that in a jar in the fridge. When you want lemonade, pour a bit into a glass and then add water to taste. It’s also good with sparkling water.
