What key test confirms the identification of genuine onion grass when its blades are crushed?

Answer

It emits a distinct, unmistakable garlic or onion scent.

Absolute positive identification is crucial before consuming any wild-growing plant. The definitive test for authentic onion grass, or wild garlic, involves crushing the foliage between the fingers. If the plant is genuine, it will release a distinct, unmistakable sulfuric aroma reminiscent of garlic or onion. If this sharp, characteristic smell is absent when the blades are rubbed, the plant is highly unlikely to be the edible variety sought by foragers. This olfactory check overrides visual similarity to other plants like chives, ensuring safety and accuracy in foraging identification.
