Frequently asked questions

When can babies eat leek?

From around 6 months. Slice it, wash out the grit, and cook until very soft before puréeing or serving in soft pieces.

Why is washing leek such a big deal?

Soil sneaks down between the tightly packed layers. Slice first, then rinse the pieces well so nobody gets a gritty mouthful.

Is leek too strong for a baby?

Cooked slowly, leek turns mild and sweet, much gentler than raw onion. It is a classic first vegetable for good reason.

Can I use the green part?

The dark green tops are tougher and can stay stringy. Stick to the soft white and pale green parts for babies, cooked until very soft.
