These things are great! They are super thin so they take up almost zero space, they are sturdy enough for even the sharpest knives, and they bend and flex so you can easily transport and pour food into bowls, plates, pots, and pans! Since they are plastic, they won't dull your knifes and they can be cleaned in the dishwasher. Lastly, the different colors allow you safely cook and cut without cross contamination, for example: blue is for fish and seafood, red is for meat, and yellow is for fruits and vegetables, etc... (Remember to never reuse a cutting board for meat or food that was used for raw meats! Make sure to get a clean cutting board, or wash the previously used one with soap and water!)
By far one of my favorite kitchen tools. It takes fine grating and zesting to a whole new level! I use it for zesting citrus, grating ginger root, mincing garlic into a paste, finely grate parmesan cheese, carrots, zucchini, chocolate and more!
This item doesn't have much to do with cooking, but it IS important to hydrate! I keep a nalgene full of water in the fridge to quickly have access to a cold beverage. I don't have to worry about a cup, I don't have to worry about ice, and I don't have to worry about making more trash in our world! If you have something like this available in the fridge, you will be more inclined to drink the water than grab a 'convenient' can of pop or bottle of juice. These bottles are BPA free and easy to travel with. So do your part for the earth and stop using non-reusable water bottles and help out your body too by drinking more water!
