Our daughter loves the onion family of foods.
The other day, we were at the farmer's market, and she reached down and grabbed part of the top of a bunch of leeks. We figured that she'd put it in her mouth and spit it out. No. She stripped it of all its green (putting much of itself on herself), and reached for more. If you want to make her happy, give her a piece of leek to chew on.
Then, we were out at Cafe Hon, and she grabbed a piece of raw onion off M's plate. Kid kept a death grip on that ring of onion through dinner, through a trip to the bookstore, and part of the way home. She treated it like it was the most delicious thing in the universe.
Today, at the farmer's market, M gave her a bite of her spicy lentil bread, and Ruth would fuss for more as soon as she finished a bite. Not an onion, but still noteworthy.
I'm going to try making her roasted garlic cubes for baby food. But M will have to change those diapers.
