Scrub carrots well. Using a vegetable peeler, slice the carrots lengthwise into long, thing ribbons. Place into a 1-quart / 1 liter glass container.
In a measuring cup combine the vinegar, water, maple syrup, salt and ginger, and stir to dissolve the salt. Pour over the carrots and top up with more water as needed to cover them completely. Place in the fridge for 24 hours and enjoy the next day.
