To use these salad bowls in your everyday life, you just have, before the first use, to proceed to a small preparation :
1. Spread olive or peanut oil inside of your salad bowl. 2. Let soak overnight night 3. Rinse warm water 4. Let dry your salad bowl without returning it
That's it ! You can use your salad bowl and mix salad and vinaigrette now ! Of course, food as beets or spices as safran or curry, will slightly color your salad bowl but without transmitting any particular taste.
To wash it, please no dishwasher but a good rinsing with very warm water and a small blow of sponge will be enough (you can, if you wish it, use a washing liquid but it is globally useless.
