A handful of ingredients and a little time in the fridge are all you need to make this shiozuke cucumber tsukemono with a delicate balance of salt, sweetness, and umami. No fancy equipment required.
Add 2 cups water, 2 tablespoons sake, 15 grams salt, 8 grams evaporated cane sugar, and 3 grams konbu to a zipper bag and swish the mixture around to dissolve the salt and sugar.
