Tuberous chervil or bulbous chervil!

The tuberous chervil, “cousin” of chervil, is a vegetable plant that you should be wary of before enjoying it. Indeed its leaves are very toxic ... It is its roots that are eaten.

 Chervil is a nutritious vegetable rich in vitamins. When it comes to cooking, we cook the roots like potatoes. But it's not steamed that root chervil will perform at its best. Prefer cooking with juice, in a meat broth.

It can also be done by double cooking, cooked in salted water and seared in butter… In 2 stages!
