Allow them to use their clean hands to rub chopped raw kale before adding it to a salad. This is called “massaging” the kale. It helps to soften the leaves. This is a great way to encourage them to try new foods!
- Select: Choose dark colored kale bunches.
- Store: Store kale in a plastic bag in the coldest part of the fridge for 3-5 days.

Kale Chips
Bake kale in the oven to make kale chips. Kids can help rip kale into bite-sized pieces. Toss with olive oil and a sprinkle of salt. Place kale pieces on a cookie sheet. Bake in the oven at 375°F until they are crispy, about 10-15 minutes.
Garden Connection
Planting
Kale is a cool season plant and can withstand frosts and snowfall, but it doesn’t love the summer heat. Plant seeds early in the spring about ½ inch deep and 8 inches apart. You can also plant again 6-8 weeks before the first fall frost for a late season harvest.

Harvesting
Harvest kale when several leaves have developed. Cut older, larger leaves and allow younger leaves to keep growing. You can continue to harvest kale through the season.
