Select the cucumbers you want to use. Many recipes specify the Kirby cucumber, but you can use whatever variety you want. If you are cutting the cucumber into spears, a smaller variety works better so they stand as soldiers around the jar. If you are cutting them into slices, it's more important that the seeds be closely packed in the fruit.
Cut your cucumbers, then lay them on a tray or put them in a bowl. Add the salt and thoroughly coat each piece. Set them aside while you prepare your sterile jars and pickling solution.
Rinse them off and lightly dry the cucumber before packing your jars.
