When can babies have mustard?

Mustard is bold, tangy, and worth knowing well, because it is a recognized food allergen. It shows up as tiny seeds in Indian tempering and as a sharp condiment in European kitchens.

How to use mustard in baby food

Temper the seedsYellow, brown, or black seeds turn nutty and mild once they pop in warm oil. Stir the flavored oil into lentils or vegetables.

Introduce it on its ownBecause mustard is a recognized allergen, offer a little by itself first, then watch for any reaction over the next day before mixing it into other meals.

Go easy on the condimentPrepared mustard, the yellow squeeze bottle kind, often carries salt and vinegar, so use only a little for babies.

Is mustard safe for babies?

Mustard is a recognized food allergen, a priority allergen in Europe and Canada, though not one of the US big 9. Introduce it deliberately, on its own like any allergen, and watch for a reaction. The seeds are safe from around 6 months once cooked in oil, where they lose their raw bite. Prepared mustard often contains salt and vinegar, so use only a little and skip added salt for babies under 1.
